Overview
Sirung is located at the NE end of a volcanic massif with multiple centers that extends 14 km NE from the southern end of Pantar Island. The volcano is truncated by a 2-km-wide caldera whose floor often contains one or more small lakes. Much of the volcano is constructed of basaltic lava flows, and the Gunung Sirung lava dome forms the high point on the caldera's western rim.
A number of phreatic eruptions occurred from vents within the caldera during the 20th century. Forested Gunung Topaki, the high point of the volcanic chain, has a small summit crater and lies ~3. 5 km SW of the active crater area.

About the Photo
The steaming summit caldera of Gunung Sirung volcano is seen here from the eastern caldera rim. Sirung volcano lies at the NE end of a 14-km-long line of volcanic centers forming a peninsula at the southern end of Pantar Island. A lava dome (center) at the western side of the caldera forms the summit of Gunung Sirung volcano; other cones along the chain to the SE increase in height. The 2-km-wide summit caldera has been the source of small phreatic eruptions during the 20th century.
