Karangetang (Api Siau) is one of Indonesia's most active volcanoes.  Twentieth-century eruptions have included frequent explosive activity that is sometimes accompanied by pyroclastic flows and lahars.  Lava dome growth has occurred in the summit craters; collapse of lava flow fronts has also produced pyroclastic flows.   Photo by Volcanological Survey of Indonesia.
