Caused by the magma under the crust was soft pressure, insert a crack to the surface world. With strong eruptions or explosive intensification occurred.What is ejected from a volcano when a volcano explodes, the magma steam? Rock debris and dust of gas is ejected from the crater (magma if you are ejected from the Earth surface is called lava, but if it is still under the surface of the Earth is called MAK.)Where there is a chance the volcano occurred. Joints between the place stays as likely the most volcano occurred. Specifically, where is the address of the plate tectonics. Beneath the ocean floor into the crust under parts of the continent. Because the crust plate tectonics to burrow down into the melt becomes a magma. Then insert it on the surface of the Earth at easier. The area away from the seam between the crust might formed volcano, which caused by the magma has been pushed up by a crevice in the rock layers.For example, geologists found in Lampang province, Thailand. There were areas where magma has been pushed up by insertion in a crevice of the stone floor, and there are some. The volcanic eruptions occurred, but not much violence. "
