ภูเขาไฟระเบิดเกิดจากการปะทุของแมกมา

Volcanic eruptions caused by the blast of the explosion (magma) often have a sign out front to know, such as the earthquake in the area around the vibration occurs, have a sound like thunder. The sound comes out it is due to the motion of come.When the explosion sprayed via maekmachathuk crater and out through the side of the volcano and from the crevice of a volcano when it comes up to the surface, lined the Earth called lava (lava) coming under globe are lined with very high pressure, compared to lava burst to the surface of the Earth to have a high temperature up to 700-1250° c. The intensity of the volcanic blast, most as a result of the viscosity of come. The major components that affect the viscosity of a silica (SiO2).

Volcanic eruptions caused by the eruption of magma (magma) before the eruption usually a signal that causes the page to fall like earthquakes in the surrounding area. Vibrations Sounding like thunder The sound output is caused by movement of magma
when the explosion occurred. Magma is sprayed out of the crater and into the slot on the side of the volcano and from the crevices of volcanoes when magma comes to the surface is called lava (lava) magma beneath the earth there will be pressure. very high in comparison with lava that came to Earth to temperatures up to 700 - 1250 ° C, the intensity of the volcanic eruption mostly as a result of the viscosity of the magma. The key components affecting the viscosity of the magma is silica (SiO2).

The eruption of volcano magma (magma) before the explosion often sign to fall, such as the earthquake in the surrounding area. Vibration noise like thunder.When the explosion. The magazine is generated through the crater and out of the side channel of the volcano and from fissure volcanoes when magma up to the surface of the earth is called the Lava (lava).700 - 1250 degrees Celsius. The severity of the volcanic eruption most as a result of the viscosity of the magma. Major components affecting the viscosity of the magma is silica (SiO2).
