Ongoing Kilauea volcanic eruptions and Mauna Loa periodic eruptions provide scientists and leisure observers the opportunity to witness the formation of a series of wonderful geological features, including new Thinker Cones, Sparkling Pits, Lava River, Splashes I will. The fountain Island of Hawaii consists of five volcanoes, which are part of a linked island of volcanoes that actually move from the northwest to a fixed hot spot in the mantle and is formed within 70 million years. The lava rising from this hotspot by 60 to 70 m below the ocean floor is currently accelerating the ongoing eruption of Kilauea volcano in the park. The Hawaiian islands are more than 2,000 miles away from the nearest continent and are the world's most geographically isolated island group. The Hawaii Volcanoes National Park is located at the southeast end of the smallest and largest island at 19 ° north latitude. Many biological groups that are common in the mainland have never traveled well in Hawaii. The descendants of those who arrived, survived, and duplicated evolved into an impressive array of native Hawaiian species. This unique phenomenon is beyond the majority of the territory of the Earth - even the Galapagos Islands. Therefore, this park is an ideal life lab for evolutionary research. Volcanic topography creates a noticeable height gradient in the park, from Mauna Loa's vast alpine crater to the coast where the wind blows up to 13,677 feet above sea level. The trade wind brings extreme rain to the park, supporting a diverse range of living areas and habitats. The seven ecological residential areas include coastline, lowlands, medium-high forest areas, tropical rainforests, highland forests and forest areas, high mountains and high mountains / wind energy contained in the park boundary. The park is one of the few nature reserves in Hawaii that protects habitat from the sea to the top of the mountain. The Hawaii Volcanoes National Park was designated as an International Biosphere Reserve in 1980, and was designated as a World Heritage Site in 1987. In 2012, the Hawaii Volcanoes National Park was portrayed in the beautiful region series in the fourth quarter of the United States. On May 10, 2018, the park was opened to the public on the summit of Kilauea volcano including the visitor center and the park headquarters due to the explosion of the Hallemauma crater, toxic ash clouds, and earthquakes and road damage. However, a part of the park including the visitor center was opened to the public on September 22, 2018. Located on the Island of Hawaii, Hawaii Volcanoes National Park is one of the most unique and naturally diverse places on the planet, holding unique volcanic features in this area, early human history, and conventional flora and fauna I interpret it. The park is very important, it has also been awarded the International Biosphere Reserve (1980) and World Heritage (1987) titles. By protecting the two most active volcanoes in the world, Kilauea and Mauna Loa, and their natural environment, there are front seats to see new lands from volcanic eruptions and to look at ancient Hawaiian architecture and culture . , Life and landscape Volcanic eruptions can be divided into two broad categories: explosive volcanoes like the Mount St. Helens and volcanic eruptions such as the Hawaii Volcano eruption. The most active volcano in the world, Kilauea volcano in Hawaii is usually a non-explosive volcano (although there is an explosive explosion). The eruption usually results in a slightly flowing lava flow, splash cone, lava fountain. Another non-explosive volcanic activity is flood basalt. The lava flow from this type of eruption is squeezed out of the crack and covers a wide area. Because people are rarely ruined, these explosive eruptions are the least dangerous type of volcanic eruption (Francis, 1993). However, they are destructive and may have a global impact. The following is a list of volcanic disasters. Please click on

Volcano is the Earth's crust opening that allows lava, gas and debris to escape to the surface. There are the most active volcanoes in Alaska, Hawaii, California and Oregon, but there are also active volcanoes in other states and regions. Volcanic eruptions include lava and other debris, flow rates up to 100 miles per hour, destroying all of that road. Volcanic ash may move 100 miles and cause serious health problems. With volcanic eruption the following is possible. Ask local disaster management evacuation and housing planning, and potential protection against ash content Learn about the community warning system. Volcano Notification Service (VNS) is a free service that sends notifications about volcanic activity. Please sign up for a reminder at https://volcanoes.usgs.gov/vns2/ If you need to evacuate immediately, or if the service is interrupted, please obtain the necessary supplies in advance. Remember the specific needs of everyone, including medicine. Do not forget the needs of pets Avoid the valleys downstream and downstream of the volcano. The rubble and the ash are carried by the wind and gravity If you have enough supplies, you can take a temporary shelter from volcanic ash. Cover vents and tighten doors and windows If you are outdoors, stimulate the skin and protect yourself from falling ash that may damage the airways, eyes, and open wounds. Please use a passed, certified mask like N95. The Centers for Disease Control and Prevention (CDC) has instructions from manufacturers on a list of certified masks and how to use the mask. Send text messages and use social media to keep in touch with family and friends. After the disaster, the telephone system is usually very busy. You can see emergency calls Please do not drive in heavy ash. If you drive it, the volcanic ash will ignite and the engine and the vehicle may stall. If you have problems with breathing, please avoid contact with ash. I am indoors until I say the authorities are safe to go out Do not get on the train to get rid of ashes unless you are under guidance or training. If ash should be removed, ash will smooth the surface so be very careful. Be careful not to add extra weight to overloaded roof Complex volcano is one of the most dangerous volcanoes on earth. Hundreds of thousands of years of complex volcanoes have been formed by multiple eruptions. The volcanic eruption forms a composite volcano that is layered to a height of several kilometers. Some layers may be formed by lava, but others may be ash, streams of rocks and volcanic debris. The compound volcano also accumulates a large amount of thick magma that blocks the inside of the volcano and causes it to explode on a large volcanic eruption. A larger caldera like the Yellowstone Crater is incredibly powerful and can cover the entire American ash. Geologists have identified three major types of volcanoes. There is a shield shaped volcano formed by low viscous lava that can flow over long distances. There is a volcanic conical volcano formed by the eruption of lava, ash, rocks formed around the crater. However, the last type is a complex volcano, the most famous volcano in the world (and the most dangerous volcano) in the world. Hundreds of thousands of years of complex volcanoes have been formed by multiple eruptions. The volcanic eruption forms a composite volcano that is layered to a height of several kilometers. Some layers may be formed by lava, but others may be ash, streams of rocks and volcanic debris. Complex volcanoes also accumulate large amounts of thick magma, block the interior of volcanoes and explode it during volcanic eruptions. There are various kinds of volcano such as shield volcano, compound volcano, dome volcano, cinder corn. However, when children are made to draw a volcano, in most cases, a picture of a composite volcano will be taken. Reason? The compound volcano forms the most common steep cone shape in the picture. They are also related t

Volcano In this article we will define and explain the volcano including volcano types, volcanic strata, volcano elements (lava, rock fragments, gas etc.). This article also explains the volcanic activity around the world. What is a volcano? Volcano is a vent on the earth where lava and natural gas are emitted. Lava from the volcano forms a hill or mountain range around the spout. Lava may flow out as a viscous liquid or it may squirted from the jet as solid or liquid particles. Shield volcano is the largest volcano on the earth and actually looks like a volcano (in other words, it does not calculate the flow of the flood basalt). Hawaiian Shield Volcano is the most famous example. Shield volcano is almost completely basalt, and it is a lava flow which flows very much during the eruption. For this reason, these volcanoes are not steep (you can not accumulate fluids that tend to flow down the mountain). If water enters the crater in some way, the shield volcanic eruption will only explode. . Shield volcano is the result of high magma supply rate; from the moment of occurrence, lava is very hot with little change. Shield volcanoes are a common product of hot volcanic activity, but they can also be found along volcanic arcs associated with subduction or all alone. According to the State University of San Diego, Thinder cone volcanoes (also called volcanic cones) are the most common types of volcanoes and they are what we consider as a normally symmetric conical volcano. They can occur as a single volcano on either side of a volcanic or shielded volcano, or as a secondary volcano called a "parasitic cone." Lava fragments in the air called tephras are discharged from vents. According to the US Geological Survey, the lava is rapidly cooled and falls with the ash accumulating around the vents, creating a crater at the top of the mountain. The Thinder cone volcano is very small, typically only 300 feet (91 meters) high, at most 1,200 feet (366 meters). They can accumulate in a short period of months or years The crater is an opening exposed on the surface of the Earth that releases the volcanic material. Every volcano has a central vent under the crater of the volcanic peak. The volcanic cone structure or building is constructed by a nearly symmetrical collection of lava and / or pyroclastic material surrounding this central ventilation system. The central spout leads deep into the magma reservoir. Magma reservoir is the main storage place for eruptive substances. As volcanic flanks are inherently unstable, they typically include a crack that descends towards a central vent or a shallow horizontal magma reservoir. Such cracks sometimes work as conduits to erupt magma sources and erupt along the sides of volcanic buildings. These volcanic eruptions can produce cones of volcanic material called parasitic cones.

Volcanic volcanoes can be described as structural disasters occurring in many parts of the world. The distribution of the volcano is closely related to the position of the global structural plate boundary. Today, there are about 500 active volcanoes all over the world. Volcano of the map in the map indicates that the North America and South America West Coast (along the Rocky Mountains and the Andes) and many Far East countries (Japan, China, etc.) occur in the coast of. Volcano In this article we will define and explain the volcano including volcano types, volcanic strata, volcano elements (lava, rock fragments, gas etc.). This article also explains the volcanic activity around the world. What is a volcano? Volcano is a vent on the earth where lava and natural gas are emitted. Lava from the volcano forms a hill or mountain range around the spout. - Volcano Expedition I. Introduction Volcano: (called the crater) one or more peaks or hills formed by the accumulation of material ejected from the opening of the earth's surface. The term volcano sometimes refers to the vent itself. Most volcanoes are steeply sloping, but flat terrains, plateaus, or even plains may be gradual slopes. Lava and volcanoes are thought to be accidents caused by coal bed burning. The term volcano, magma means the terrain caused by the eruption location or hard lava, we know now that there remains in the vicinity of the crater. Active volcanoes are mountains that may explode or abandon volcanic material. The magma reservoir is buried beneath the surface of the earth, volcanic pressure and heat accumulate, followed by volcanic explosion volcano 1. Introduction Volcano: Defines mountains and hills formed by accumulation of one or more explosives. There are more openings on the surface of the earth (called craters). The term volcano sometimes refers to the vent itself. Most volcanoes are steeply sloping, but flat terrains, plateaus, or even plains may be gradual slopes. Altitude volcanoes are most famous,

In this article we will provide information on Hawaii Volcano, which is the second largest volcanic island in the world, next to Iceland. Beautiful landscapes and wildlife not only draw interest in this area, but the unique nature of Hawaii Volcano and the island itself make this area very important. Information on how Hawaii must adapt to volcanic disasters from the history of the island will be provided to maintain the dwelling life of the area. With these thoughts in mind, I will first set up a scene to solve the region's background information and make this area very special. Then I will move on to the way ... show more history of the content Basically, the main fact that makes the Hawaiian Islands very unique and worthy of study is that almost all mountain ranges are built entirely by volcanic activity, and each island is a huge volcanic summit. These superior qualities drive research on how the island itself was made in response to the curiosity behind some of the world's most luxurious volcanoes. The basic theory of plate tectonics is that all volcanic activity (physical geology) should occur between lithospheric plates. However, the Hawaiian Islands bent this rule by being in the middle of the Pacific plate. Hawaii Volcano is known as a volcano in the plate. This seems unlikely as it will destroy plate building rules in addition to hotspots. Wilson suggested that the Pacific plate moved northwest at the mantle melting point of the mantle, which provides magma for the Pacific plate moving while remaining relatively stationy forming a Hawaiian island chain (ocean volcano) did. To prove this proposal, the structure of the Hawaiian Islands must be consistent with the source of the hot spot. this is For those unfamiliar with the history of Hawaii volcano it is important to note that there are five volcanoes on the island. Kilauea is considered one of the most active volcanoes in the world. Mauna Loa Island also lives on the island, and this volcano is often called "a sleeping giant". Mauna Loa is considered to be the world's largest active volcano, and the area is only Tam Mountain (extinct volcano). Mauna Loa is considered to be the only Hawaiian volcano in Kilauea, and it is actively supplying from the bottom magma reservoir. Kilauea volcano is not only the youngest volcano in Hawaii but also a shield shaped young volcano located on the southeast side of the huge Mauna Loa volcano, the world's most active volcano. . It has continued to erupt without interruption since 1983 (now at the exit of Eastern Rift Valley Pu'u'O'o) due to its oral or written history. According to Hawaii's legendary flame goddess Bailey's hometown, there is a huge crater at the top of Kilauea volcano, and there is Hare mama in the center. Until 1924 there was also a lava lake. There are peaks and Franck lava eruptions occurring along Kilauea, often along two lift zones extending southwest and east. And it stretches to the sea on both sides of the volcano. About 1500 years ago, this 3 × 5 km crater was divided into several stages.

Influence of Volcanic Gas and Earth System on Volcanic Gas Most of atmospheric gases originally come from inside the earth. The gas in the magma dissolves by the high pressure of the surface of the earth, but the surface pressure decreases and the dissolved gas expands and escapes. As the volcano erupts, gases such as sulfur dioxide, carbon dioxide, chlorine, argon, sulfur, carbon monoxide, fluorine, and water vapor are released into the atmosphere. Many of the gases released during a volcanic eruption may help the Earth, but many gases can damage the Earth system. Shield volcano is the largest volcano on the earth and actually looks like a volcano (in other words, it does not calculate the flow of the flood basalt). Hawaiian Shield Volcano is the most famous example. Shield volcano is almost completely basalt, and it is a lava flow which flows very much during the eruption.

Volcano is one of the most interesting and dangerous phenomena in nature. In this article, we will learn and explain some of the basic physics controlling volcanic behavior. Magma is composed of three major components of viscous silicate melt * crystal * volatile substance (gas) and interacts as one of the main focus of petrologists and volcanologists. Hawaii is not one of the most important and active volcanoes in the world, it is still the third largest active volcano in Hawaii. The other two volcanoes are in Hawaii Volcanoes National Park. Kilauea volcano is known as one of the most active volcanoes in the world and has been on volcanic eruption since 1983 (Physical Geology). Monaroa is known as the world's largest volcano. These three main volcanoes will reflect many aspects of the very unique Hawaiian volcano. And those For those unfamiliar with the history of Hawaii volcano it is important to note that there are five volcanoes on the island. Kilauea is considered one of the most active volcanoes in the world. Mauna Loa also lives on the island This volcano is often called "a sleeping giant", and it is not dormant, but it is decades since the volcano showed activity. Mauna Loa is considered to be the world's largest active volcano, the area is Tam massif, extinct volcano. Mauna Loa is thought to be the only Hawaiian volcano in Kilauea and is still being actively supplied on a large scale from the lower magma. Mauna Loa rose to 136,79 feet above sea level and it is the 66th peak in the United States. It is generally thought that it is the largest active volcano on the planet, and Mauna Loa erupted about 700 thousand years ago. This volcano is registered as a UNESCO World Heritage Site of Hawaii Volcanoes National Park and is monitored by several observation platforms such as Hawaii Volcano Observatory. Volcano is one of the most interesting and dangerous phenomena in nature. In this article, we will learn and explain some of the basic physics controlling volcanic behavior. - The name of the volcanic volcano on Earth comes from the Vulcano of Greece. "For the ancient Greeks, Vulcano was Hierra Hefeiestou ... For ancient Romans it was a fortified place in Vulcan. Bullard 1984) Although myths have disappeared since then, the name Vulcano still has all volcanoes It is a symbol of.

As the concentration of silica increases, resistance (viscosity) to magma flow increases. Compared to basaltic magma, andesite magma with high silica content constitutes the majority of composite volcanic clastic material. This silica-rich and volatile magma is the reason to separate the composite volcano from the shield volcano. Anshan magma dominates fragments of fragments, but some magma invades into a cone like a window frame or a dam. Because of this multiple invasion, the strength of the structural framework can be obtained, so the composite volcano is higher than the composite volcano consisting only of debris material. Shield volcano is the largest volcano on the earth and actually looks like a volcano (in other words, it does not calculate the flow of the flood basalt). Hawaiian Shield Volcano is the most famous example. Shield volcano is almost completely basalt, and it is a lava flow which flows very much during the eruption.

They can accumulate in a short period of months or years Volcanoes can be classified by type. Structure and composition determine the type of volcano. Shield volcano is a dome-shaped mountain of lowland formed by lava and flows easily and covers a wide area. Thinder cone volcanoes are the simplest form, and they are normally discharged from the vent with a bowl shaped crater at the top of the mountain. Complex or layered volcanoes are the most common type, they are towering mountains, steep slopes, alternating interior rock layers and magmatic layers. The two basic classifications of volcanoes are based on the type of volcanic eruption they produce: explosive (or middle) and quiet (or crack). Explosive volcanic eruptions are caused by the accumulation of gas under high viscosity (thick and slow flowing) magma deep inside the volcano. Volcanic eruptions are rapid and violent, often releasing lava, volcanic ash, and volcanic substances. Quiet eruptions usually emit lots of lava during long cracks and breaks.

Myths and legends are everywhere. Once upon a time there was an ancient Greek myth and legend. Almost everything including volcanoes has myths and legends. Myths they created, why did they get out? Myths and legends of various gods dominate their volcanoes. Almost every volcano has a story. Volcanic legends and myths are very numerous, ranging from Hephaestus to Vulcan, and among them. Knowing to think about volcanoes as people make myths is very interesting; the myths of volcanoes are as attractive as other myths. There are many god stories about the rise of volcanoes and temperatures. One of the most persistent is a false indication that ash produced by eruptive mountains is the main factor of current climate change. That is, there is a relationship between the volcano and the changing environment. There is evidence that rapid climate change has led to past volcanic eruptions, and conversely past volcanic eruptions have led to climate change. Of course, human activities do not affect the eruption of these volcanoes in the Pacific "ring of fire" area. Because of the plate structure, there are more volcanoes. But sudden climate change is related to volcanic activity in certain parts of the world. A study published in the minutes of the National Academy of Sciences in September found that glacial retreat at Antarctica was related to a series of volcanic eruptions of 200 years. Myths and legends are everywhere. Once upon a time there was an ancient Greek myth and legend. Almost everything including volcanoes has myths and legends. Myths they created, why did they get out? Myths and legends of various gods dominate their volcanoes. Almost every volcano has a story. Volcanic legends and myths are very broad, ranging from Hephaistus to Vulcan and recent climate change. Volcanic activity is a fairly common event on the planet. Generally, there are 50 to 60 small volcanic eruptions everyday. These volcanic eruptions are registered in the volcanic explosion index (VEI) as well as the Richter scale earthquake. It ranges from 0 to 8, 0 is the weakest, and 8 is mass extinctionable. The main volcano erupts usually every 100 to 200 years. Every 10 thousand years, A

Volcano is an important part of the earth system. Most of the Earth 's atmosphere, water, and crust are carried by volcanoes, and volcanoes continue to collect Earth' s substances. Volcano eruption is common. Everywhere on the planet, more than a dozen people occur frequently and there are 100 occurrences in a year (Loughlin et al., 2015). Volcanic topography and volcanic emissions are diverse, reflecting the large and complex nature of the interaction process controlling magma production, storage, rise and eruption. The volcanic eruption is influenced by the tectonic setting, the nature of the crust, the history of the volcano. However, the method of volcanic eruption varies widely, but volcanic eruptions are controlled by a common set of physical and chemical processes. Super volcano is a volcano that can cause volcanic eruption of 1000 km 3 or more. This is huge when compared to normal volcanic eruptions (1 km 3 volcanic material spewing from Mount St. Helens). Super volcanoes differ from ordinary volcanoes in that they form cavities called caldera. The caldera is usually surrounded by higher ridges and is less frequent occurrence. This video explains the basics of super volcano and introduces the potential impact of Yellowstone (video). If the yellow stone occurs again, the magma will be thrown into the 50 kilometer atmosphere and almost all life exceeding 1000 kilometers will be killed by falling ash, lava flow and volcanic eruption. More than 1000 km 3 of lava flows down from the volcano and is thick enough to cover the entire US 12.5 cm

Not all the volcanoes are the same. Volcano comes from various geological processes. For example, the volcano in Figure 8 seems to be similar in shape, but it has very different characteristics. Mountains of St Helens and Mt. Fuji (SF Figures 8A and C) are in the subduction zone. Because the generated lava is a complex mixture of continental crust and oceanic crust, they are called complex volcanoes. Complex volcano rarely erupts, but when they occur they explode explosively Mauna Kea (SF Figure 8B) is a hot spot and the hot magma source is a very shallow point on the surface of the Earth. The Hawaiian islands are located in the middle of the Pacific plate and are formed as the plate moves over this hotspot. Mauna care is a dormant volcano. Kilauea is another volcano on Hawaii Island and is currently active. It is one of the most lasting volcanic eruptions and usually produces a slow, gentle lava flow. There are many volcanoes in Iceland (eg SF Figure 8D). It is a very unusual volcanic continent as it is formed where the center lift valley of the sea actually rises above the surface of the water. Eyjafjallajökull and Mt. Saint Helens are complex volcanoes, usually causing steep and explosive volcanic eruptions. In Figure 8 of SF, you can see the explosion of Eyjafjallajökull (SF in Figure 8D) and the result of explosive explosion of the volcano. St Helens (SF Figure 8A) Find the volcano in Figure 8 on the map. What kind of plate boundary or plate these volcanoes are? Why do you think there are different types of volcanic eruptions on hot volcanoes and subduction zone volcanoes? Please explain your answer from a plate movement perspective. (Hint: Please check the composition of magma and lava. Let's study what the volcanic eruption in Iceland is like. Compare those volcanic eruptions with subduction zones or hot volcanic eruptions. How are they similar? Wrong? Figure 8 Which volcanoes are erupting now? When do scientists predict that these volcanic eruptions will cease? Which volcano in Figure 8 is active but has not erupted yet? When do scientists think they will break out again? Indeed, you can compare different types of volcanoes with soccer team players. The tall and impressive compound conical volcano is like a quite powerful and confident quarterback. A wide and low shield shaped volcano seems to be a strong ruler of the team. Besides, although it is growing rapidly, the smaller Thinder Coehn volcano seems to be a compact runway with our team moving quickly. Let's take a closer look at these three main types of volcanoes. A complex conical volcano, also called "layered volcano" or simply "compound volcano", is a conical volcano composed of layers of lava, ash, and rock fragments. Complex conical volcano is a wonderful place to grow to a height of over 8000 feet. St. Helens Mountain and Rainier Mountain discovered in Washington State are impressive examples of multiple volcanoes. One of the most common types of volcanoes is the burning cone. Due to the low risk compared to other types, the Thinder cone grows only to about 1,000 to 1,200 ft. Unlike other types of volcanoes, that is, unlike shield volcano and compound volcano, thinner cone is usually formed with one opening. The opening of the cone cone is a conical structure and the steep slope is formed by debrisynder discharged near the chimney / vent. Another type of volcano is shield volcano. Unlike the Thinder cone, the size of the shield volcano is very large. However, it is not as big as it looks. This is because the eruption of shield volcanic lava is not accompanied by pyroclasts (emission of gas and particles).

Volcanoes are openings on the surface of the planet allowing hot lava, ash, and gas to escape from the bottom of the earth's surface. The name "volcano" comes from the Vulcan Fire God of Roman mythology. Volcanoes are like huge safety valves, releasing the pressure generated inside the earth. The Hawaiian Islands are made up of 5 volcanoes There are four kinds of volcanoes classified by activity level. An "active" volcano is a volcano that erupts often. There are about 500 active volcanoes on the earth except for the volcano at the bottom of the ocean. "Dormant" Volcano is a volcano that has not erupted for many years, but there are still some activities in it. "An extinct" volcano is a volcano that is no longer active. Volcanic eruptions occur when hot rocks and lava erupt from a volcano; the geysers and hot springs are actually just volcanoes. They are caused by groundwater trapped by the heat of the volcano. The lava in the volcano is called magma and it is called lava when it flows out. The temperature of fresh lava ranges from 700 degrees Celsius to 1,200 degrees Celsius, and it generates hot incandescence when flowing. The most dangerous volcanic eruption recorded was the eruption of Mount St. Helens in Washington. The highest volcano in the world is Ohos del Surardado, Chilean volcano. The largest volcano in the world is Hawaiian Muanro. Volcanoes generally concentrate on the edge of the continent along the chain of islands or form long mountains on the ocean floor. The majority of the world's active volcanoes surround the Pacific Ocean and form a "circle of fire". Volcanic eruptions can have a serious impact on the land and its surroundings. The damage left by them led to completely destroying the surrounding landscape. In the past 500 years, about 20,000 people died due to volcanic eruption. The building is destroyed, people are homeless, people are killed, plants and animals are destroyed, and toxic gases released from the volcano can cause diseases such as death and pneumonia. But everything related to volcanoes is not negative. The crust of the earth, A large amount of magma did not erupt but cooled down below the surface. It makes fertile soil and contributes to cultivation. The volcanic ash that erupts from the volcano increases the soil fertility by adding nutrients to the soil. Groundwater heated by magma can be used as geothermal energy. Most metal minerals such as copper, gold, silver, lead and zinc are extracted from the magma deep inside the extinct volcanic roots. As scientists research more and more volcanoes, they can measure the level of volcanic activity. With this information, you may not be able to prevent volcanic eruptions, but at least large-scale human life damage can be avoided by evacuating personnel in time. What I remember from my nephew's visit is to check Inside Out. In the first video, a solitary volcano formed an island with love until another volcano reacted and joined the first erupting volcano. In the theater, my wife and I keep hands and smile at each other and remind me of their island making. Then I noticed that my nephew was crying quietly and my mouth became narrow with pain - and she did not do anything to stop the tears on the other side of my wife. What comes from a volcano * Lava * Tephra (rock fragments) * Why does the gas eject? When magma and natural gas find escape routes, the volcano erupts. Volcanic eruptions may be mild and / or violent. Active volcanic type * - often * inject a dormancy - a specific period, also known as sleep * do not erupt during extinction - erupted during a volcano of at least 100,000 years or more? The volcano is a volcano that is open on the surface of the planet or in the Earth's crust, allowing hot magma volcano to be a conical structure emitted by lava. The domed structure not only adds to natural beauty but it makes it more spectacular, and on the other hand they are very dangerous as it helps to b

Volcanoes are natural phenomena on the surface of the earth and molten rocks and gases escape from below the surface (Tarbuck, 139). It is very interesting to observe these volcanoes and observe those amazing events and majestic lava eruptions. The word "volcano" is thought to come from Volcano Island Vulcano in Italy's Aeolian Islands, and the name of the volcanic island comes from the myth of the name of Vulcan, Roman Vulcan. Volcanic rock consists of several types that can extrude several types of magma and emit various gases. These extruded materials can affect the structure and atmosphere of the earth. I forgot to mention important things, but complex volcanoes also form part of the earth's surface. Complex volcano has a conical shape with steep top area and gradually sloping side and is structurally almost symmetrical (Tarbuck, 141). These volcanoes are rich in magnesia and emit gaseous magma. And it is very viscous and has a short travel distance. These three kinds of volcanoes occupying the earth seemingly have different physical characteristics and behavioral changes. Volcano eruption is one of the most dangerous and troublesome natural disasters. Several factors were considered during these volcanic eruptions. Each type of volcano discussed above has a different form of lava: one is very fluid and the other is very viscous. Lava can be extruded in various forms as it is extruded from a volcano. One format is Pahoe Ho. Pahoe Hui, which is common in Hawaii Volcanoes, is a kind of smooth and viscous lava, which causes condensation of lava as lava is released from the volcano (Williams, 32). Another form of lava is lava called aa. This lava consists of coarse, coarse, thorny pieces and measures the pieces separated into different pieces (Williams, 37). Aa flows coolly and can move at speeds of 5 to 50 meters per hour (Tarbuck, 145). Lava can also form blocks Volcanoes can be classified by type. Structure and composition determine the type of volcano. Shield volcano is a lowland dome type mountain formed by lava, it is easy to flow and covers a wide area. Thinder cone volcanoes are the simplest form, and they are usually discharged from vents with a bowl shaped crater at the top of the mountain. Complex or layered volcanoes are the most common type and they are towering mountains, steep slopes, alternating interior rock layers and magmatic layers. The two basic classifications of volcanoes are based on the type of volcanic eruption they produce: explosive (or middle) and quiet (or crack). Explosive volcanic eruptions are caused by accumulated gas under high viscosity (thick and slow flowing) magma caught in the deep part of the volcano. Volcanic eruptions are rapid and violent, often releasing lava, volcanic ash, and volcanic material. Quiet volcanic eruptions usually emit a large amount of lava during long cracks or interruption. What comes from a volcano * Lava * Tephra (rock fragments) * Why does the gas eject? When magma and natural gas find escape routes, the volcano erupts. Volcanic eruptions may be mild and / or violent. Active volcanic type * - often * inject a dormancy - a specific period, also known as sleep * do not erupt during extinction - erupted during a volcano of at least 100,000 years or more? The volcano is a volcano that is open on the surface of the planet or in the Earth's crust, allowing hot magma volcano to be a conical structure emitted by lava. The domed structure not only adds to natural beauty but it makes it more spectacular, and on the other hand they are very dangerous as it helps to bring about huge disasters. As an example, the word volcano originated from the name Balkan, which means Roman Balkan. The volcanic eruption was thought to be one century ago.

As volcanoes erupt, they emit a mixture of gas and particles into the air. Some of them, such as ash and sulfur dioxide, have a cooling effect as they reflect the sunlight (or the substances they cause) away from the earth. Others such as carbon dioxide cause global warming by increasing the greenhouse effect The effect of cooling is particularly noticeable, and a large explosion can sunburn particles to the stratosphere. It is difficult to judge that the cooling observed after a specific eruption is definitely the result of an explosion, but checking the global average temperature change after multiple eruptions proves strong ties. Regarding greenhouse gases, according to estimates of the UK Geological Survey and the US Geological Survey, carbon dioxide totaling about 100 to 300 million tons annually is released from underwater and athletic volcanoes. This is massive, but it is only about 1% of the amount of fossil fuel released only by humans. Normally, immediately after a volcanic eruption, the cooling effect of a single volcano will dominate, but the effect of global warming will last for a long time. Therefore, the importance of each depends on the time frame considered. In very large volcanoes in 2011, there is a possibility that the temperature has drastically decreased in 2012, but in 2100 it warmed slightly It is suggested that people trying to argue against human climate impact believe that volcanoes emit carbon dioxide rather than humans. This is totally wrong. As the UK Geological Survey said: "The current contribution to the carbon dioxide load in the atmosphere by volcanic eruption is relatively small ..." The Guardian's article is licensed under Creative Commons Attribution - No Derivative Works 0 UK: England & Wales License. The long-term impact of volcanoes arises from a simple geographical location. Because the volcano is a huge mountain, the impact on the climate is the same as that of a normal mountain. This leads to a rain shadow effect (explained in the Continental Movement section) that functions like a volcanic building. Until the volcano erodes it will continue to affect the climate. This may last thousands of years. Volcano has a big impact on climate. This effect is either short term (volcanic ash) or long term (rain shadow effect). Biology can also be affected by this. For example, the desert area may develop rapidly on the leew side of a new volcano. Extinction will be a big threat if you can not adjust your life In 1783, Benjamin Franklin initially assumed that major volcanic eruptions will affect climate after the eruption of Raki volcano in Iceland. Ironically, since most of the material spewed by this eruption remains at the bottom of the atmosphere, Franklin has the right idea, but the volcano is wrong. In the top four panels, Figure 1 shows the effect of four low-latitude volcanic eruptions on global average temperatures between the 1880s and the 1980s. Individual volcanic eruptions show a lot of change in cooling time (although volcanic eruptions occurred at different times of the year), the four volumetric eruptions indicated as "complex" in the fifth group The average of the volcano shows many months in the next three years (especially cold summer) A volcanic eruption is a geological event that has influenced global explosions for years. Scientists estimate that such last eruption took place 74, 000 years ago, and it is ten thousand times stronger than Mount St. Helens. Large amounts of rocks and ashes were blown into the air causing six years of winter volcanoes and 1000 years of ice age, massive deforestation, devastating famine, and human extinction. Scientists estimate that super eruptions will occur every 100,000 years.

"... To date 99.9% of all species have been extinct." (Benton 1) After 160 million years of governance, the dinosaurs were governed by fire and ice. 65 million years ago, the biggest volcanic eruption ever happened in India, effectively destroying dinosaurs by blowing poisonous gas and ash, effectively killing the plants and destroying the food chain by the sun We stopped. The dinosaur died of starvation. Some people think the volcano has killed the dinosaurs. When the volcano erupts, it is the idea that the dinosaur will not give plants and plants necessary for survival, because it will destroy a lot of dust and debris and block the sun. When it occurred, the lava was thought to immediately burn some dinosaurs and destroy the entire ecological food web. A more general assumption is the idea of ​​comets. Some scientists believe that a huge comet hits the Earth and that many dust and debris can not fly out and grow plants to block the sun. Because large herbivores require enough plants to survive, they disappear first. Without a large herbivorous animal as a food source, a huge carnivore quickly dies. The comet itself crushes many dinosaurs. Only small animals and insects can tolerate this disaster A: Nemesis theory is one of the theories "come from outer space" of dinosaur extinction. The idea is that every twenty six million years the comet will approach the Earth, bring more debris to hit the Earth, change the weather and kill many animals. Perhaps they killed dinosaurs, pterosaurs, and large reptiles 65 million years ago. In related theory, there is evidence that asteroids lead to extinction and huge asteroid craters were discovered in Mexico about 65 million years ago. However, I do not know if dinosaurs are enough, or whether dinosaurs have disappeared or have completely disappeared or not already happened. The truth is that we will not lead to extinction of dinosaurs, it may even be a combination of asteroids, volcanoes, moderate climate change, and even diseases. This is a mystery! (Don Lessem) The extermination of dinosaurs due to the influence of asteroids does not precisely know how dinosaurs were extinct. However, scientists have guessed for decades that led to the death of the dinosaurs. Its possibilities range from asteroids to volcanoes, to climate change. - Summary of the effects of meteor and asteroids According to theory, years ago a huge meteor destroyed all the dinosaurs on the earth. Since that time, scientists have found evidence that millions of meteors hit the earth. However, recently, we are still threatened by the influence of another meteor, so scientists are trying to find the exact way to track and predict the meteor's trajectory. This is the meaning of most of my project.

It includes all volcanoes that erupted within the past 10,000 years, or volcanoes that are considered potentially active, and many extinct volcanoes. If you have interesting information about volcanoes (or areas), especially images you want to share, news, witness accounts, please contact us or send us the materials for confirmation. Quick Link: Volcano News | Today's Volcano | Active Volcano Map | Volcano Glossary | Volcano Photo | Volcano Webcam Hawaii is not one of the most important and active volcanoes in the world, and it is still the third largest active volcano in Hawaii. The other two volcanoes are in Hawaii Volcanoes National Park. Kilauea volcano is known as the most active volcano in the world and has been on volcanic eruption since 1983 (Physical Geology). Monaroa is known as the world's largest volcano. These three main volcanoes will reflect many aspects of the very unique Hawaiian volcano. Those For those unfamiliar with the history of Hawaii volcano it is important to note that there are five volcanoes on the island. Kilauea is considered one of the most active volcanoes in the world. Mauna Loa Island also lives on the island, and this volcano is often called "a sleeping giant". Mauna Loa is considered to be the world's largest active volcano, and the area is only Tam Mountain (extinct volcano). Mauna Loa is considered to be the only Hawaiian volcano in Kilauea, and it is actively supplying from the bottom magma reservoir. Mauna Loa rose to 136,79 feet above sea level and it is the 66th peak in the United States. It is generally thought to be the largest active volcano on the planet, and Mauna Loa began erupting about 700,000 years ago. The volcano is part of the UNESCO World Heritage Hawaii Volcanoes National Park and is closely monitored by several observation platforms such as the Hawaii Volcano Observatory. When studying volcanoes in the world it is important to understand the classification of volcanoes and how they work. Several factors are considered when trying to classify volcanoes into groups, such as recent activities, duration of volcanic eruption, scale, potential impact, and so on. Although listening to it is not common, volcanic eruptions are not uncommon. Volcano classification refers to the life cycle that can usually be defined as activity, extinction or dormancy. However, volcanoes can also be classified by the composition of the structure, which means that it can be a shield, a cone or layered volcano. Finally, they can be classified as they may be quiet or explosive.

Volcanic volcanoes on Earth's name come from the island of Vulcano, Greece. "For the ancient Greeks, Vulcano was Hierra Hefeistow ... for the Romans it was a fortress of Vulcans, for the Vulcano they were the god nest of fire" (Bullard 1984) Since then the myth has disappeared However, the name Vulcano is still a symbol of all volcanoes. "Volcanoes are places where both lava, solid rock, or natural gas originate from the interior of the planet" (Scarth 1994). The volcano is in the Earth's crust, releasing hot gas, char and lava. Volcanic eruption and invasion have two kinds of activities. There are two types of eruption activities, volcanic plateaus and mountains of local volcanoes, and invasive activities are described as window frames and dams. The type of activity obviously determines the danger of the volcano. The protruding volcanic mountain range releases all three volcanic materials and it is a much more dangerous volcanic disaster because it may cause secondary disasters such as volcanic landslides, landslides, large floods and so on. A prominent volcano example of Columbia's Nevado del Luis issued 22,000 deaths in Almero's town due to volcanic landslides caused by the melting of glaciers. Sulfur dioxide concentration can be measured by outgassing; this indicates the presence of upward magmas through rocky cracks Volcanic volcanoes on Earth's name come from the island of Vulcano, Greece. "For the ancient Greeks, Vulcano was Hierra Hefeistow ... for the Romans it was a fortress of Vulcans, for the Vulcano they were the god nest of fire" (Bullard 1984) Since then the myth has disappeared However, the name Vulcano is still a symbol of all volcanoes. - Volcanic volcanoes are holes or holes in the Earth's crust where a melted hot magma outside the local shell is forced to reach the ground. Magma is gathered in the room under the Earth's crust, pressure rises and is pushed out through cracks and cracks, forming a conduit leading to the ground. Hot air tries to escape, but it is trapped in magma Burning lava extends the vibrant image of the towering volcano, but it does not share all stories of volcanic rock and lava. Well, it can be defined as a vent of the Earth's crust through lava, rock fragments, hot steam and gas it can squirting. In other words, volcanoes are the way the Earth releases a little vapor. * Ultra high temperature particles emitted from a volcano are coming from the deep part of the earth's surface and the temperature is to evaluate the main influence of the more serious influence of the volcanic eruption and the range of the secondary influence ... You can be. Volcanic eruptions are natural disasters, whereas volcanoes are a type of earthquake that occurs in faults between structural plates that destroy the boundary. The main effect occurs after a disaster, before death or correspondence such as building collapse or destruction. Minor impacts after disasters such as reduction or reduction of agricultural crops

The volcanic destruction that can be created in the "volcanic road" on the volcanic road is a good explanation for the damage the volcano can cause. This movie also made me understand the importance of volcanologists. When studying volcanoes, we can predict the next volcanic eruption and save many lives. On January 3, 1983, the most active volcano in Kalapana of Kileaua erupted. The lava was shot at 1500 feet in the air, discharging 100 thousand gallons per minute, accounting for 400,000 cubic yards per day. Landslides due to volcanic activity are some of the most devastating types. The volcanic lava rapidly melts the snow and rapidly accelerates large amounts of rocks, earth, ash, and water on the steep slope of the volcano and destroys something on that road. These volcanic muds (also called volcanic mud) reach long distances when leaving the side of the volcano and may damage the structure of a flat place around the volcano. In 1980, the eruption of Mount St. Helens in Washington caused a massive landslide in northern volcano, the largest landslide in history. The volcanic destruction that can be created in the "volcanic road" on the volcanic road is a good explanation for the damage the volcano can cause. This movie also made me understand the importance of volcanologists. When studying volcanoes, we can predict the next volcanic eruption and save many lives. On January 3, 1983, the most active volcano in Kalapana of Kileaua erupted. - Volcanoes are truly dangerous. It is an animal or a plant. In the volcanic eruption, hot lava is released from the volcano. After the volcanic eruption, the lava will cool. After the lava has cooled, it becomes a hard rock called the igneous rock. When the lava falls into the water, it cools and forms a landscape. Example: Hawaii does not destroy people next to a volcano Unless a volcano occurs, it is an island. Lava and volcanoes are thought to be accidents caused by coal bed burning. The term volcano, magma means the terrain caused by the eruption location or hard lava, we know now that there remains in the vicinity of the crater. Active volcanoes are mountains that may explode or abandon volcanic material. The magma reservoir is buried beneath the surface of the earth, volcanic pressure and heat accumulate, followed by volcanic explosion volcano 1. Introduction Volcano: Defines mountains and hills formed by accumulation of one or more explosives. There are more openings on the surface of the earth (called craters). The term volcano sometimes refers to the vent itself. Most volcanoes are steeply sloping, but flat terrains, plateaus, or even plains may be gradual slopes. Altitude volcanoes are most famous,

What do you think about the dinosaur's death? Did the asteroid collide with the earth or there was food shortage? Death and destruction deep inside the earth are more frequent. One example is a volcano. There are over 3,000 active volcanoes in the world. The most devastating volcano originated 251 million years ago and its lava flow covers about 1 million square miles It is now Siberia and destroys the majority of its lives. Volcanoes are openings of the Earth's crust where lava, ash, and gas blow. Tens of thousands of people are being killed by centuries volcanoes, whether it is ash, deadly gas or lava itself. Other methods of killing volcanoes come from hot ash clouds, flying stones, mudslides, tides and collapsed roofs. About 60 volcanoes erupt each year. Not only the people living in the volcano died of the eruption, but scientists who studied the volcano also died. Last month, the US Geological Survey listed 15 volcanoes that are currently erupting or may erupt. There are two volcanoes in 15 volcanoes: Alaska, Hawaii, Guatemala, Ecuador, Montserrat, Italy, Russia, Indonesia, Philippines. Volcanoes do more than just destroy what they produce. Some geologists say the early Earth is made up of mountains formed by lava. Hawaii is an example of an underwater volcano that creates islands and land. Most of Hawaiian islands are made from underwater volcanoes. As you can see, volcanoes have advantages and disadvantages, but mainly have strengths and weaknesses. Another argument in the volcanic world is whether government funds are used to monitor volcanoes and prevent volcanoes. This method of studying volcanoes costs a lot of money and there is a possibility that many scientists will lose their lives.

We will provide PDF copy of your screen reader Tsunamis are often underestimated in the Mediterranean and parts of Europe. In the Lisbon earthquake and tsunami in 1755 (due to the Azores - Gibraltar conversion fault) and the Calabria earthquake in 1783, history and present (about risk assumption) are important. Take the 1908 Mexican earthquake and tsunami. Tsunami kills over 123,000 people in Sicily and Calabria and is one of the most deadly natural disasters in modern Europe. Examples of tsunamis affecting landslides and the British Isles in the Norwegian Sea include not only waves due to earthquakes but mainly landslides and weather tsunamis. If you are trying to evaluate the danger of a tsunami at a specific location on the planet, you need to first understand how the tsunami is occurring. Earthquakes and volcanoes have created the majority of the tsunami, and plate tectonics explains the causes of earthquakes and volcanoes. Therefore, we start with the review of the simplest plate construction in the world. Plate tectonics is a magnificent unified theory of earth science, but in reality it is not so old. In fact, since a college freshmen consultant wrote a benchmark paper outlining the mathematical model of the plate structure, in a sense I was only a generation of "generations" removed from the era before plate manufacture. ** Shameless plug alarm **: Please choose EARTH 520 to gain a deeper understanding of the history of plate structure theory Natural disaster: What is a natural disaster? Natural disasters are natural events that pose a danger to human life and property. "Natural disaster" is a generic term for events such as volcanoes, earthquakes, and tsunamis. Types of natural disasters include avalanches, earthquakes, floods, forest fires, hurricanes / typhoons / cyclones, landslides, thunderstorms / blizzards / ice storms, tornadoes, tsunamis, volcanoes and so on. Below is a brief explanation of these natural disasters. Many of these natural disasters are studied in more detail in the follow-up course of this module.

Krakatoa is a crouching volcano until 20th May 1883. On this day, many people erupted for the first time. The volcanic eruption was so devastating that the window suddenly broke in a nearby civilization. By August 11, the three vents of the volcano often got out. On August 26, four volcanic eruptions occurred within several hours, the volcano was finally divided and seawater was poured into the magma reservoir. It caused an explosion and it was possible to listen to Australia 3,500 kilometers away and destroy the majority of the island. The sound produced is the largest ever. The waves from the explosion spread 7 times around the world and the sky became dark in a few days. This is said to be the most serious volcanic eruption of the present age. It is believed that no one was murdered for the first explosion, but an estimated 37,000 people were killed as the tsunami destroyed the surrounding villages, in addition to overheating the volcanic ash across the ocean It was. A few weeks after the incident reported that the body of the deceased person was floating in the sea and it was discovered that cockroaches flushed volcanic pumice off the east coast of Africa one year after its occurrence It was. The catastrophe was a catastrophe, but due to this incident, people created many amazing sights. It is said that spectacular sunsets have occurred all over the world due to light reflection of dust particles floating in the air. In addition, the famous picture "Scream" of Edward Munich in 1893 is believed to be an accurate depiction of the Norwegian sky after the volcanic eruption. Absolutely unstoppable destruction created by Krakatoa is a decisive example of absolute power. In that era, conflicts over power, power, and knowledge continued endlessly. However, no matter how many incidents occurred, no one on Earth was ready to confront Krakat's unstoppable force. Throughout history history, numerous dictators and leaders insisted that they had absolute power, but eventually their reins came to an end. However, Krakatoa volcano still exists today. The island has been renamed Anak Krakatau, it is completely disinfecting his life and growing to 13 cm a week. As the threat of time and the violence in the surrounding world eventually conquer, this indicates that no one can dominate with absolute power alone. Volcanic volcanoes, and other famous destructive volcanoes such as Krakatoa and Vesuvius are also compared with famous volcanoes such as Krakatoa and Vesuvius. Volcano says he is "still volcanoes" and the adverb "stationary" reminds the reader that despite the lack of volcanic activity, the devastating nature of the volcano remains unchanged . Indeed, the volcano continues to remind the reader that Krakatoa has "locked the fists in the earth" for centuries, but when "anger is already full" he said "shocking the world Give it. " This picture means hidden extreme anger. These comparisons are very important. Because these famous volcanoes seem to be quiet. Some of the world's most famous volcanoes are complex volcanoes. Some of the most devastating volcanic eruptions in history come from them. For example, Mount St. Helens, Pinatubo Volcano, and Krakato Volcano are just a few of the complicated volcanic eruptions. Famous mountains in Japan, mountains Rainier in Washington state, mountain Kilimanjaro in Africa, etc. are famous landmarks which are not erupted recently. Absolutely unstoppable destruction created by Krakatoa is a decisive example of absolute power. In that era, conflicts over power, power, and knowledge continued endlessly. However, no matter how many incidents occurred, no one on Earth was ready to confront Krakat's unstoppable force. Throughout history history, numerous dictators and leaders insisted that they had absolute power, but eventually their reins came to an end. However, Krakatoa volcano still exists today. The island has been renamed Anak Krakatau, it is completely disinfecting his life and g

In my article, I will consider various case studies to explore why certain dangers are more predictable than other risks. According to the report, between 1974 and 1978, 497 natural disasters caused human injuries. There were 1,897 occurrences in the past 5 years, about 3 times increase. Between 1974 and 1978, 195 million people died for disasters and emergency relief; in the past 5 years there were 5 billion such victims in the past five years. During emergency response, conditions and risks are often unpredictable (nonlinear) than planned activities. In general, if conditions and risks are predictable (linear), they must be handled appropriately in the standard operating procedure. In some emergencies, this may also be correct, and preparation and training correspondence is sufficient to manage this situation. In such a case, the operator can manage the risk without the aid of external assistance, or with the help of an alternative team that can prepare and intervene in a short period of time. All countries face the risk of weather, water, and climate, but not all countries have the ability to predict and respond to them. In some countries, the Early Warning System (EWS) was able to mitigate the effects of natural disasters, but the scope of such systems may be limited. Fortunately, in some countries we devised a way to turn EWS into a more powerful system. A remarkable example is Shanghai Municipal Hazard Early Warning System (MHEWS), which cooperates with related municipal authorities to respond timely to natural disasters. With its success, the Shanghai Municipal Government and the China Meteorological Administration (CMA) announced an early warning center within the Shanghai Meteorological Department (SMS) to handle various types of warnings including but not limited to hydrological phenomena and weather phenomena deployed. Unlike other types of natural disasters, the risks and potential risks of volcanoes are properly positioned. Reliable forecasts can reduce damage caused by volcanoes, but these predictions only apply to well studied and fully instrumented volcanoes. Forecasts based on previous volcanic eruption statistics are too vague for certain short-term projections of volcanic eruptions. Prediction is a general announcement that volcanoes may erupt in the near future and predictions may include volcano parts that may erupt, relatively erratic statements describing the eruption time and possible types of volcanic eruptions is. Such predictions must be made publicly attentive to gain confidence from the relevant group so that they will comply with the preparatory measures reliably. In other words, preparation and planning are essential to mitigate volcanic disasters before volcanic eruption.

In Katmai National Park and Nature Reserve, there are 3,674,529.68 acres of land. It fits about 8 times in Pennsylvania. Located at the northern end of the Alaska Peninsula, Katmai National Park and Nature Reserve are made up of six active volcanoes and surrounding forests, lakes and mountains. Perhaps the most famous volcanoes are Novarupta and Mount Katmai, which are known for their 1912 volcanic eruption, Katmai National Park is in southern Alaska. It was established on September 24, 1918 to protect recently damaged areas. Katmai was designated as a national monument to preserve the features associated with one of the most powerful volcanic eruptions ever in 1918. However, the subsequent expansion and change of Katmai's position did not focus on geological activities, but focused on the importance of wildlife. Today, according to law, one of the main purposes of the Katmai National Park and Nature Reserve is to protect fish and wildlife habitat, including but not limited to high bear brown bears and their habitats , It remains harmless. Basin and water habitat are indispensable for sea bream laying. In Katmai National Park and Nature Reserve, there are 3,674,529.68 acres of land. It fits about 8 times in Pennsylvania.

This evacuation plan covers all of Shizuoka prefecture, Yamanashi prefecture, Kanagawa prefecture. These county governments are ready for the possibility of volcanic eruption. In this plan, 750,000 people need to leave the house due to lava and volcanic debris flow. A crowd of 750,000 people wonder where these people all go This flexible approach was successful while traveling to Alaska's Katmai National Park. She is headed to Brooks Camp, the most popular destination in the park. Katmai National Park is a volcanic landscape with thousands of brown bears inhabited. Galyna and her team (2 people) are planning to camp outside the Brooks camp after trying to reserve a campsite at Brooks Camp.

Kilauea located on the island of Hawaii is one of several dome volcanoes that form the Island of Hawaii. The uniqueness of these islands is in stark contrast to our understanding of global plate tectonics and volcanoes formed around the Pacific Rim volcanic zone. Kilauea and Hawaiian volcanic zones are moved by geological hotspots in the central Pacific. Thomas Yage is one of the pioneers of Hawaii volcanic activity and opened the way to the Hawaii Volcano Observatory founded in 1912. For those unfamiliar with the history of Hawaii volcano it is important to note that there are five volcanoes on the island. Kilauea is considered one of the most active volcanoes in the world. Mauna Loa also lives on the island This volcano is often called "a sleeping giant", and it is not dormant, but it is decades since the volcano showed activity. Mauna Loa is considered to be the world's largest active volcano, the area is Tam massif, extinct volcano. Mauna Loa is thought to be the only Hawaiian volcano in Kilauea and is still being actively supplied on a large scale from the lower magma. Figure 8. The Hawaiian islands are a good example of a hot spot chain. Kilauea volcano is on Hawaiian hotspot. Mount Mauna Loa is older than Kilauea Volcano and still erupts, but at a lower rate. These islands are far from the hot spot, so they are old in the northwest. Loihi is still the youngest volcano under the sea Kilauea located on the island of Hawaii is one of several dome volcanoes that form the Island of Hawaii. The uniqueness of these islands is in stark contrast to our understanding of global plate tectonics and volcanoes formed around the Pacific Rim volcanic zone. Kilauea and Hawaiian volcanic zones are moved by geological hotspots in the central Pacific. - When magma is discharged from the surface of the earth, a volcano is formed and a volcanic eruption such as ash and lava occurs. Over time, the lava will cool and form rocks on the surface of the earth. Whenever an eruption occurs, the newly formed rocks in the lava layer will continue to form until a volcano is formed

Introduction Marie Byrd Land (MBL) is a West Antarctica plot important for understanding the evolution of the Antarctic Lift System (WARS). The size of WARS is comparable to other lift systems, but it covers a wide range of ice sheets (LeMasurier, 2008). The MBL includes exposure to long-term behavior of WARS (Cande et al., 2000; Steinberger et al., 2004) and volcanic activity under the ice associated with the system damages the ice sheet in the western Antarctic, It may cause a momentary eruption (Blankenship et al., 1993). Marie Birdland is the largest volcanic area in Antarctica, about 970 km along the Pacific coast. A lift from the base of the Antarctic Peninsula to the surrounding area of ​​Ross Island can be seen along the northern end of the Rift Valley. Numerous major shield volcanoes are emphasized through ice, including Sidley Mountain, the highest volcano in Antarctica. Although many volcanoes may be relatively young and active (Berlin, Taka, Weshe, Mount Seaple), other volcanoes such as Andrew Mountain and Hampton Mountain have a history of over 10 million years Remains left untouched architectural form In the new NASA's research, we have added evidence that the geothermal heat source called the mantle plum is deep in the Maryborough area of ​​Antarctica and explains the melting of the lake and river under the ice floor. Heat source is not a new threat to the ice sheets of the Western Antarctic or an increase in threat but explains why the ice sheets collapsed rapidly in the early stages of rapid climate change and why today is so unstable It may be useful for. Experiments done at Oxford University show that the structural plate is weaker than previously thought. This finding explains the ambiguity of laboratory work and scientists have come to believe that these rocks look stronger than they do in nature. This new knowledge helps to understand how the structural plate breaks and forms a new boundary. Tectonic plates are huge rock segments that move continuously relative to one another. They form lithosphere, crust and mantle. The structural plate consists of the ocean and continental crust. The oceanic crust consists of sea and the continental crust consists of land. The structural plate forms a divergent boundary, a deformation boundary, or a convergence boundary when in contact. Volcanoes, rift valleys, mountains and earthquakes are the result of mutual movement of structural plates occurring at structural boundaries. The heat in the mantle causes convective motion of the structural plate. There are large and small structural plates. A total of seven plates covering nearly 95% of the world

Mount Shasta semester Thesis Many people know that Mount Shasta is a popular tourist attraction in the beautiful mountain ranges of California. But this mountain is more than this, it is actually this volcano. Volcanoes are dangerous, and volcanoes of this size are no exception. The volcanic eruption of Mount Shasta gives us insight about the power of this volcano and its possible damage. With this information, scientists can predict what will happen with another explosion. Shasta Mountain Well, looking at Mount Shasta, I can maintain a stable mindset when I think it is a powerful symbol of beauty, love, and great power. I know clearly that violence can only lead to violence. We absolutely have a problem, except for love we will do our best to twist as many things as possible. This is a universal law in the world, I have never felt such a strong constraint. Because this powerful mountain is an excellent symbol of the power of God, we are fighting to prove that you can master it. But no matter how much you are satisfied, before realizing that real life is related to love and brotherly love, it is a manifestation of arrogance. Mount Shasta semester Thesis Many people know that Mount Shasta is a popular tourist attraction in the beautiful mountain ranges of California. But this mountain is more than this, it is actually this volcano. Volcanoes are dangerous, and volcanoes of this size are no exception. The volcanic eruption of Mount Shasta gives us insight about the power of this volcano and its possible damage. With this information, scientists can predict what will happen with another explosion. During the winter solstice, as electromagnetic energy flows into the earth, physical phenomena occur inside and around the Shasta mountain. Those who know our golden city in the mountains of Shasta on the earth will understand what we are communicating to you. This city is an Ascension Master, and it is always a meeting place for all of us. We call it the Golden Ether City Havalanechee. It represents the glow of the 22nd god in platinum fire and brings the essence of the source of everything. It is the stage of consciousness of five dimensions that is completed. And God and Goddess are one.

Explain how to create slab components on igneous rocks of arc arcs. Let's consider the environmental arcs of the front and rear arc basins that form the subduction of the oceanic plate under the oceanic plate. Volcanic activity is concentrated in the volcanic arc and is usually almost above the leading edge of the subduction plate. Grooves are often formed where the plate encounters and begins to jump. Fisch, Meschede and Blakey), a basin where the pre-sink basin is closest to the subduction / trench and then the main arc and the far arc side is close to the receding arc is formed in a series of basins (Mitchell and Reading, 1971; Frisch, Meschede and Blakey) ). . Igneous rocks are rocks that crystallize from lava and magma. Melt consists of various components of existing rock melting in the subduction zone or inside the mantle. Because the molten metal is very hot, it will rise through the colder country rocks. As it moves, it cools and forms various types of rocks through a process called fractional crystallization. Igneous rocks can be seen on the mid-ocean ridges, arc volcanic areas or plate hot spots Explain how to create slab components on igneous rocks of arc arcs.

The uniqueness of these islands is in stark contrast to our understanding of global plate tectonics and volcanoes formed around the Pacific Rim volcanic zone. Kilauea and Hawaiian volcanic zones are moved by geological hotspots in the central Pacific. Island arcs are groups of islands or islands formed from volcanic activity along the subduction zone. Subduction occurs when marine lithosphere sinks to continental or oceanic lithosphere. Submerged rocks melt into magma in the asthenosphere and some rock surfaces surfaced to form volcanoes. On the ocean floor, these volcanoes gradually form islands. The arc of each island is next to the deep groove. The arc of most islands is part of the circle of fire around the Pacific Ocean, but it is also found in the Aegean Sea and the Caribbean Sea.

The eruption of Vesuvio is as warning as an earthquake. Interestingly, the Romans are very interested in predicting the future They have many different ways to decipher the anger they are seeing. They are good at observing "omen" with a strange vision and a healthy or unusual birth pattern. But they obviously can not see signs of a volcanic explosion. As we saw from the building of the building, the 63 AD CEZE caused great damage to Pompeii. According to the historical record, Vesuvius volcano destroyed the southern city of Pompeii in about 25 hours in the Christian era. The site is a snapshot of the well preserved life of the city of Rome, as the city was rapidly buried by volcanic ash. He also recorded the details of the victims recorded by Pliny the Younger and recorded the incident with a letter to his friend Tacitus. Pompeii was founded in 600 BC. It is slowly recovering from the big earthquake that hit the city in February, 62 CE. Shallow earthquakes that occurred from Vesuvius caused severe damage to springs and pipelines and supplied water to the cities. Reconstruction is done in several temples and public buildings. Historian Seneca recorded that the earthquake lasted for several days, seriously hurt the town of Herculaneum and subdued it after giving minor damage to the town of Naples. One of the most serious volcanic disasters occurred in the coast of Gulf of Naples in Italy. At the foot of the mountain known as "Soma Mountain" or "Vesuvius Volcano" there are two prosperous cities "Pombe" and "Herculaneum". People living in these cities are living peaceful and productive lives and they do not know that they will encounter unhappily. On 24th August, 79 Vesuvius was revived by revenge, released the gas, dropped the ashes in both cities. At night, gas-rich magma descended down the volcano, destroyed all of the way along the streets of Herculaneum. Repeated water flowed into the city, burning the debris of the volcano and filling the town of Herculaneum. Pompeii followed it, and the huge wall of the original town changed the flowing Magma river, but eventually magma unleashed its ruthless destruction of Pompeii and its people. When the whole mountain area is swallowed. Metric ton Essay.com/ Why are volcanoes active and passive from the various viewpoints of the authors?

A volcano is an opening on the surface of a planet or moon that allows warmer material to escape from its interior than the surrounding environment. A volcanic eruption will occur if this substance leaks. The volcanic eruption will be explosive and material will be sent to the sky. Or, with a calm flow of materials, calm down This picture shows the eruption of Mount St. Helens in Washington State in July 1980. Due to the eruption of the volcano, the ash was sent in the air 6 to 11 miles (10 to 18 km) and 100 miles (160 km) in Seattle, Washington. It is north. Image Source: USGS Mike Ducas These volcanic zones usually form a mountain gathered by layers of rock, ash, and other substances. The volcano may be active, dormant or extinct. The active volcano is a volcano that has recently erupted or is expected to erupt in the near future. The dormant volcano no longer causes a volcanic eruption, but it may erupt again at some future time. An extinct volcano will never occur again Lava is overflowing from Kīlauea volcano in Hawaii Volcanoes National Park. Image source: USGS Scott Hobus A volcano occurs when a substance is sprayed warmly from its interior to the surface of a planet or moon more than its surroundings. On Earth, eruptive substances can be liquid rocks ("lava" when it is on the surface, "magma" when underground), ash, ash, and / or gas. There are three reasons for magma ascending to erupt the surface of the earth. When fragments of the crust called tectonic plates slowly move away from each other, the magma rises. Magma rises to fill the space. When this happens, it is possible that underwater volcanoes will form. As these tectonic plates move relative to each other, magma also rises. When this happens, a part of the Earth's crust can be pushed deep into the inside. The crust of the earth melts due to high temperature and high pressure, rising like a magma. The last way the magma rises is hot. Hotspots are how they sound - a hot spot inside the Earth. These areas heat magma. Magma has low density. It will rise if the density is low. There are various reasons for magma to go up, but each can form a volcano. Yes, there were lots of volcanoes on other planets. Certain parts of our solar system erupts active volcanoes now! Venus and Mars are covered with extinct volcanoes. Several satellites of Jupiter, Saturn and Neptune are actually experiencing volcanic eruptions. We took these pictures with various NASA spaceships! Volcanoes have existed for centuries and will continue to have more volcanoes. Many people understand the idea of ​​volcanoes. Most people believe that it is basically a mountain, shoots lava and destroys nearby things. This assumption has been proved to be accurate in practice. Volcanoes are considered one of the most dangerous natural disasters; they can suddenly erupt and destroy everything. - Volcanic volcanoes are natural phenomena on the surface of the earth, melted rocks and gases escape from below the surface (Tarbuck, 139). It is very interesting to observe these volcanoes and observe those amazing events and majestic lava eruptions. What is a volcano? The volcano is "shape or structure (usually conical)" made by ventilation openings on the surface of the earth, through which the gas and ash associated with the magma are released, ie the released material. Through a lot of discussion about Class I volcano, I think it is not as simple as the definition. The reason is that the science and history of volcanoes is much more complicated. People like to use stories and legends to explain volcanic activity everywhere. Once upon a time there was an ancient Greek myth and legend. Volcano and almost everything there is a myth and legend. Myths they created, why did they break out. Myths and legends of various gods dominate their volcanoes. Almost every volcano has a story. Legends and myths about volcanoes are very numerous, from Hephaestus to Vulcan, and to all

Mauna Loa Island: Furious mountains Mauna Loa is the largest volcano on Earth and the largest mountain range, because it occupies nearly half of the vibrant landscape of Hawai'i. The island actually consists of five volcanoes including Kohala, Mauna Kea, Hualalai, Mauna Loa, Kilauea. Mauna Loa is located in the southern middle of Hawaii in Hawaii Volcanoes National Park, with coordinates 19 ° 5'N, 155 ° 6'W. It is 13,680 feet in altitude, but if you take measures from the actual location of the ocean floor, it is estimated to be as high as 30,080 feet. Mauna Loa Volcano Mauna Loa is located in Hawaii and means 'long mountain' in Hawaii. It is a huge Genbu shield volcano. It is one of the largest volcanoes and mountains in the world and is known as "mountain monarch". Estimated volume is 9,600 cubic miles, half of Hawaii. It ranges from the southern tip of the island to the northern area by about 120 kilometers. The length from the ocean floor to the mountaintop is 97 kilometers (60 miles), the width is 48 kilometers (30 miles), the height is 8,742 kilometers (28,680 miles).

It is 13,680 feet in altitude, but if you take measures from the actual location of the ocean floor, it is estimated to be as high as 30,080 feet. Mauna Lore or "Long Mountain" is the world's largest active volcano. In fact, it is one of the highest mountains in the world. Mountains of Monaroha and other active volcanoes on the island erupt once every two or three years and become one of the most active volcanoes in the world. Mauna Loa is called shield volcano like other volcanoes in Hawaii. This usually means that it is a gentle hillside created by a large number of turbulence occurring. The volcano erupted from the main volcano center (Knowledge Expedition Homepage) at the top of the mountain for at least 100,000 years. Hualailai is the third youngest and the oldest volcano in Hawaii. Hualalai is not as active as Mauna Loa and Kilauea, but our recent volcanic geology shows that 80% of Hualalai's surface has been covered by lava flow over the past 5000 years.

Scientists of the USGS volcanic disaster program are active in five US volcanic observatory stations. One of the main objectives of the Observatory is to become an authoritative source of inspiration for our country's volcanoes. The Hawaiian Volcanic Observatory (HVO) is the oldest of the five with a long history and has written regular articles on volcanic activity and scientific research on Hawaii Volcano. HVO's weekly magazine "Volcano Watch" was published in the 27 th year of November 2017. You can access the entire article directory and search on those websites. Post a new article every Thursday afternoon Beginning with HVO, the Yellowstone Volcano Observatory (YVO) is the latest of the five observatories, an article published every week on the first day of 2018. This new column - "History of Yellowstone Crater" - will be posted on the homepage every Monday. Like YVO's website HVO's Volcano Watch series, the YVO Chronicles have been reviewed and edited before publication. Please contact us if you would like to know about specific topics related to Yellowstone and Hawaiian volcanic activities. We absolutely will reply, you may see a long answer in a future volcano watch or an article in the Yellowstone caldera chronicle. The Alaska Volcano Observatory website (AVO) contains complete information about Alaska Volcano Cleveland Hills is in the middle of the Aleutian Islands and continues volcanic eruptions since June 17, 2015. Explosive volcanic eruption can send ash to dangerous aviation height Great Sitkin, located in the middle of the Aleutian Islands, has been erupting volcanoes since July 1, 2018. Explosive volcanic eruption can send ash to a high degree harmful to aviation The mountain of Veniaminof in the Alaska Peninsula was on the volcanic eruption since 3rd September, 2018. Seismic activity exceeds the background level and low level ash release is observed Semisopochnoi is located in the western part of the Aleutian Islands and continues volcanic eruptions since September 16, 2018. High seismic activity involves ash emissions that can threaten aircraft Since 1983, the Kilauea volcano of Hawaii is continuously erupting from Eastern Rift Valley. A small amount of lava remains in the crack of the east lift zone of Kilauea. Are you interested in which volcano poses a hazard to the United States? The US Geological Survey started a volcanic disaster plan to create volcanic risk maps for the United States and Canada. Investigation of risk map: Is there a volcanic risk near the United States? Please click the non-green volcano icon on the map - where is the volcano? What makes them risk to people in these areas? Do volcanoes change over time? how is it? Use USGS information on one of the dangerous volcanoes to send an e-mail to a fictitious friend near the volcano, asking if you should pay attention, evacuate it or avoid it (dangerous lava or ash) indicate. Outdoor? ) Many volcanoes around the world are subject to disaster research and some of the most notorious volcanoes have been designated as volcanoes for 10 years for intensive hazard studies. Popocatepetl should be registered in the volcano list for 10 years within the amazing range of 30 million people around it, including Mexico City. Volcanic Debris Density Flow is driven by gravity, rock debris and hot gas movement fast, ground-enclosing mixture. This mixture forms a dense fluid moving along the ground and the density drops as the particles fall to the ground. The behavior of the fluid depends on the solids concentration (ie solid gas ratio) versus the amount of hot gas. Dense flow of density is called "volcanic debris flow" and it is practically non-turbulent and confined to valleys. Low density flow is called "volcanic debris" and may spread to hills and valleys like a hurricane. The environment, volcanoes can compromise all these things through many hazards caused by volcanoes. Volcanic mudflow, floods, landslides, volcanic de

The outer shell of the earth consists of a series of structural plates that move on the surface of the earth. Volcanoes are sometimes formed in areas where plates are deposited. Volcanoes can also be formed in the middle of the plate, magma is a so-called "hot spot" and rises until it occurs at the ocean floor. The Hawaiian islands are formed by such hot spots in the middle of the Pacific plate. The hot spot itself is fixed, but the section is moving. Therefore, as the plate moves to the hot spot, an island of the island forming the chain of the island of Hawaii is formed. The Hawaiian Islands form an archipelago spreading in the vast area of ​​the North Pacific. The archipelago consists of 132 islands, atolls, coral reefs, shallows, shallows, and seamounts, 1,500 miles from the northeastern Cré Atoll and the southeastern Hawaiian Island. The Hawaiian islands are often called paradise, and these islands are often used as remote tropical tourists from all over the world. Most of the people visiting the Hawaiian Islands are looking for a peaceful holiday without understanding the complicated and corrupted nature of the island. According to American colonialism, indigenous people's culture and religion of Hawaiian indigenous people were seriously affected. The country basically sells land and culture to tourists and non-local commercial companies for economic benefits. Kilauea located on the island of Hawaii is one of several dome volcanoes that form the Island of Hawaii. The uniqueness of these islands is in sharp contrast to our understanding of the global plate tectonics and the formation of volcanoes around the Pacific Fire Ring. The linkage between Kilauea and Hawaii Volcano is driven by the geological hotspot in the central Pacific Ocean. - When magmas are released from the surface, they form volcanoes and cause volcanic eruptions such as ash and lava. Over time, the lava will cool and form rocks on the surface of the earth. Whenever an eruption occurs, newly formed rocks in the lava layer will continue to form until a volcano is formed All the islands of Hawaii are formed by volcanic activity. In short, these islands are actually the tips of the huge mountains beneath the sea and are produced by huge volcanic eruptions. Moving from the northwest to the southeast, each volcano is getting smaller. The oldest in the northwestern part of the island was formed about 80 million years ago. The southernmost island volcano in Hawaii is still active today, and you can see the establishment of a new land for many days a year.

Volcanic eruptions influence the majority of the Earth 's ecosystem from delicate dust input to thick deposits near the volcano. In this chapter, we are studying the influence of volcanic ash deposits on the land using recent volcanic eruption examples. "Tephra" is a generic name for volcanic substances in the air, but ash is limited to 1000 years. Alien species may severely hinder the recovery of ecosystems. The erosion process affects volcanic ash by redistributing volcanic ash, thereby reducing the thickness of volcanic ash in some areas, but there is also the possibility of erosion rates exceeding 100,000 tkm - 2 years. Dust input thick tephra deposits have a significant impact on agriculture, and the toxicity of F is common in volcanic areas. The soil formed from the volcanic ash-based matrix is ​​mainly Andisols, and its colloidal part consists mainly of short-range ordered minerals and metal-humus complex. Andisols are normally fertile soils with high carbon deposition capacity. Interdisciplinary long-term research on influence and correspondence of volcanic eruption Several types of volcanic eruptions - lava, ash (ash, volcanic ash, volcanic eruption, volcanic rock), and various gases emitted from craters and cracks - have been distinguished by volcanologists. These are usually named after famous volcanoes where they are observed. Some volcanoes may show only one characteristic type of eruption during activity, but other volcanoes may show all types of volcanoes with a series of eruptions. There are three volcanic eruptions. The most noteworthy thing is the magmatic eruption. Magma eruption involves depressurizing gas in magma and advancing it. The Phratomagmatic volcanic eruption is another type of volcanic eruption caused by gas compression in magma, opposite to the process of magma activity. Volcanic eruptions influence the majority of the Earth 's ecosystem from delicate dust input to thick deposits near the volcano. In this chapter, we are studying the influence of volcanic ash deposits on the land using recent volcanic eruption examples. "Tephra" is a generic term for volcanic substances in the air, but ash is limited to substances with particle size less than 2 mm. The effect of tephras depends on the properties of tephra, such as crystallinity, chemical composition, particle size. The interaction between the height of the vegetation and the depth of the sediment has a significant influence on the influence, and factors like surface roughness are also important. Low growth Arctic, Takayama, desert ecosystems are more sensitive than high vegetation and forests. Recovery time ranges from several years to over 1000 years. Alien species may severely hinder the recovery of ecosystems. Andisols are normally fertile soils with high carbon deposition capacity. Volcanic ash is produced during volcanic eruptions and consists of pulverized coal, mineral, and volcanic glass fragments less than 2 mm (0.079 in) in diameter. The term volcanic ash is also commonly used to refer to all explosive eruptive substances (more precisely called tephra) containing particles larger than 2 mm. Volcanic ash is formed during an explosive volcanic eruption as dissolved gas in magma expands and escapes violently into the atmosphere. The power of escaping gas crushes the magma and pushes it into the atmosphere, where it solidifies into volcanoes and glass fragments. As magma erupts, ash will also be formed when magma comes in contact with water, causing water to vapor and causing magma to break. Once in the air, the ash will spread in the winds thousands of kilometers away.

Explosive volcanoes can also cause deadly landslides and volcanic landslides. A powerful and fast volcanic mud flow path scrolls down to clear everything on the street In Washington in 1980, after the hibernation in 123 years, the mountain of St Helens erupted. The explosion destroyed 230 square miles (370 square kilometers) of forest in a matter of minutes and burned. Volcanic eruptions emit large amounts of hot ashes, natural gas, steam, and rocks, and these huge trees are capped at 15 miles (24 km). Volcano erupts in various ways. Some people exploded like Mount St. Helens. The explosive eruption is very powerful, shoots 20 miles (32 kilometers) of particles, throws eight tons of rocks half a mile (0.8 kilometers), and causes massive landslides. Explosive volcanic eruptions also generate large amounts of hot volcanic debris, ash, and gas, thereby causing it to topple everything on its path. Explosive volcanoes cause most volcano-related death A volcano like Mauna Loa Volcano in Hawaii is full of enthusiasm. Lava was poured or flowed instead of a violent explosion. Death by volcanic eruption is rare, as people can usually exceed lava. However, there are people who are too close or trapped and not escaping. Flowing lava burns, melts and destroys everything you touch, such as farms, houses, roads. The volcanic eruption transformed the landscape. Volcanoes will be destroyed, but we will also make mountains, islands, and eventually incredibly fertile lands. Volcanic eruptions can damage hundreds of miles away. Volcanic ash can cause damage to aircraft engines, destruction of crops, pollution of water, and damage to electronic equipment and machinery. The ashes were paved, filled all, sometimes even collapsing the building. Mount St. Helens produced more than 490 tons of ash, dropped to 22,000 square miles (56,980 square kilometers), causing problems in cities 370 miles (600 kilometers) away. The surface of the earth is called the "crust". The crust is divided into chunks called "plates". Magma flows under the crust. Volcanoes are usually formed along the edge of the plate It may be of the same popularity, but when it is below the surface it is called "magma". When it is on the surface it is called "lava". Shield volcanoes are the largest volcanoes on the planet and actually look like volcanoes (that is, they do not calculate the flow of flood basalts). Hawaiian Shield Volcano is the most famous example. The shield volcano is almost completely basalt and it is a lava flow which flows very much during the eruption. For this reason, these volcanoes are not steep (you can not accumulate fluids that tend to flow down the mountain). When water somehow enters the crater, the volcanic eruption of the shield only explodes, otherwise they are characterized by a low explosive fountain which forms a synder corn and splash cone in the crater, but the volcano 90 % Is lava. Shield volcano is the result of high magma supply rate, lava is very hot with generations, little change. Shield volcanoes are a common product of hot volcanic activity, but can also be found in the volcanic arcs associated with subduction or all of them. The crater is an opening exposed to the surface that releases volcanic substances. Every volcano has a central vent under the crater of the volcanic peak. The volcanic cone structure or building is constructed by a somewhat symmetrical accumulation of lava and / or pyroclastic material surrounding this central ventilation system. The central vent is deeply connected with the magma reservoir. Magma reservoir is the main storage place for eruptive substances. As volcanic flanks are inherently unstable, they usually include cracks descending towards the center exhaust or shallow horizontal magma reservoir. Such cracks sometimes serve as a conduit to erupt magma sources and erupt along the sides of the volcanic building. These volcanic eruptions may produce pyramids of volcanic material called parasi
