Gunung Sundoro is located immediately NE of Sumbing volcano. The hill in the foreground is part of a large deposit resulting from a prehistoric debris avalanche that traveled around 20 km prior to formation of the present-day volcano. Explosive eruptions have occurred from both summit and flank vents in historical time.
