The Supervolcano in Indonesia; The Tondano Caldera

Within Indonesia is a supervolcano which few people know about. I am not referring to the Lake Toba supervolcano, but instead a different volcanic complex on the island of Sulawesi. There, the 30 kilometer long and 20 kilometer wide Tondano caldera is present, which formed entirely in the last 1 million years. It contains numerous young vents and is surrounded by frequently erupting volcanoes such as Soputan, which may share part of a massive underlying magma chamber.
