Geological summary

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.

From Wikipedia

Mount Sirung is an active volcano complex volcano located on Pantar Island in the Alor archipelago of the eastern Indonesian province of Nusa Tenggara Timor. The crater rim can be reached by an easy hike from the village of Kakamauta. Inside the crater is a large sulphurous crater lake and several active steam vents. The last major eruption occurred 1970, and regular gas and clastic eruptions have occurred since 2004. A small eruption beginning May 12, 2012 triggered an evacuation of an area within a 1.5 km radius of the caldera.
