Volcano (volcano) is vented to the molten rock of the Earth's crust. And the effects of various complications through volcanic crater up. And related phenomena, such as volcanic gas output (fumeroles) and Hot Spring (hot spring) are an interesting phenomenon, one of those geological processes them. Generally, cone-shaped volcano. Called the crater (crater) cone is above the crater. Passed on to the trunk chimney pipe or conduit magma chamber beneath the earth. During the eruption is water vapor, dust, volcanic ash (ash), molten rock called lava rock fueled by the chimney. The magma chamber is located deep below the earth's surface into a pan containing hot molten rock material. This could either intruding into the crust, or erupt on the surface are two types of eruption throws (effusive) and explosive eruptions (explosive), which the eruption of Mayon Volcano in the Philippines in this section is the eruption throws. (Effusive)
the causes of the eruption
of the volcano eruption process that is not yet a clear understanding. Geologists estimated that the accumulation of heat, making the area very much magma, steam and gas deposits are growing. Which caused pressure high temperature at one point, it will explode. Rate the intensity of the eruption depends on the severity of the explosion. The vapor pressure And the viscosity of lava If the magma is very viscous The intensity of the explosion is very serious as well. The volcano eruption Not only lava flowed only provides gas, steam, dust, ash and smoke is coming out with a roll down. The steam is condensed into water. Remove dust and ash that fell into a mud flooded with runoff in the lower foothills. If the volcano is covered in snow. It will melt the snow
