The Sirung is located at the northeastern end of a line of volcanic centers 14 km long, which forms a peninsula south of Pantar Island.

This low volcano, 862 meters high, is truncated by a caldera 2,000 meters wide; the floor is occupied by one or more acidic lakes. This site was the seat of phreatic eruptions in the 20th century; the last eruption, probably of phreatic nature,  took place in May 2012.
