Well basically, the volcano is on a plate margin. The pacific plate and Indo-Australian plate collide with each other and one plate is pushed under another. Because of the heat underground, the rock melts and becomes magma. When there is too much magma, it pushes it's way up through the cracks and finally it erupts. The cracks in the rock, (overground) come from when the plates are pushing against each other.
