Plate Tectonics

The Eurasian and Australian Plates form Mt. Tambora. This is a Convergent Plate Boundary. The Australian Plate which is sliding below the Eurasian Plate is getting soaked with water which aids in melting the mantle wedge, this forms magma. Often the magma cools and a volcano does not form. However, when magma reaches the surface a volcano is formed.
