A Little bit about Indonesia...

   Indonesia is located in the "Ring of Fire" which is a geographical feature of the ocean floor which creates explosive volcanism. This makes the land of Indonesia highly unstable and there is always the possibility of a volcanic eruption. These volcanoes form because of the contact between the Indo Australian Plate and the Pacific Plate become subducted under the Eurasian Plate, causing the underlying magma to be pushed out and volcanoes to form.
