9 May-15 May 2012

CVGHM reported that on 8 May a three-hour long ash eruption from Sirung was accompanied by loud sounds and incandescence that reached 10 m above the crater. An ash plume rose 3.5 km above the crater and drifted N, producing ashfall up to 4 mm thick near the crater. During 9-12 May white plumes rose 30-50 m above the crater. A sulfur odor was reported in areas up to 3 km away on 12 May. That same day CVGHM raised the Alert Level to 3 (on a scale of 1-4) and recommended that visitors not approach the volcano within a 2.5 km radius.

Based on a report from a ground-based observer and analyses of satellite imagery, the Darwin VAAC noted that on 12 May an ash plume rose to an altitude of 3 km (10,000 ft) a.s.l. and drifted about 95 km SW.

Sirung volcano is located at the NE end of a 14-km-long line of volcanic centers that form a peninsula at the southern end of Pantar Island. The low, 862-m-high 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 have occurred from vents within the caldera during the 20th century. Forested Gunung Topaki, the 1390-m high point of the volcanic chain, lies at the SW end and contains a symmetrical summit crater.
