Mount Merapi eruption 2006?

Question

I am doing a Geography project and I need information on the causes of the mount merapi eruption 2 years ago. Like the tectonics movement and the trigger factor that led to the eruption.

Answer 1

Mt Merapi is a strato volcano and has erupted because of the subducting oceanic fault underneath its plate causing buildup in the mantel.  The heat and pressure buildup in the mantel causes the upward force of gas, ash, and lava to violently erupt through the volcano.
