Volcano

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 parasitic cones.

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.
