Volcanoes

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.
