Small short-lived ash eruptions in May 2012 and July 2015

Small eruptions from Sirung were reported in May 2012 and July 2015. These were the first reported eruptions since 1970 from the volcano at the southern end of Pantar island, which sometimes has a crater lake and a history of phreatic activity.

Activity during 2012. The Indonesian Centre for Volcanology and Geological Hazard Mitigation (CVGHM) reported that on 8 May 2012 a three-hour long ash eruption that was accompanied by loud sounds and incandescence material that reached 10 m above the crater. An ash plume rose 3.5 km above the crater and drifted N, causing ashfall up to 4 mm thick near the crater. During 9-12 May white plumes rose 30-50 m above the crater.

On 12 May an ash plume rose to an altitude of 3 km and drifted about 95 km SW, and a sulfur odor was reported in areas up to 3 km away. 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. During 13-18 May 2012 diffuse white plumes rose 10-50 m above the crater. Seismicity was elevated during 12-17 May then decreased through 23 May, although levels remained above background. On 25 May the Alert Level was lowered to 2 (on a scale of 1-4).

CVGHM reported that during 1-13 June 2012 diffuse white plumes rose 30-70 m above the crater. A sulfur odor was occasionally noted at the Sirung observation post. Based on seismic activity and visual observations, on 15 June CVGHM reiterated that the Alert Level remained at 2 (on a scale of 1-4). On 7 September 2012 the Alert Level was lowered from 2 to 1 (on a scale of 1-4).

Activity during 2015. Based on analyses of satellite imagery and wind data, the Darwin VAAC reported that on 7 July 2015 an ash plume from Sirung rose to an altitude of 1.5 km and drifted 85 km SW. On 8 July an ash plume at an altitude of 1.5 km drifted 55 km W.

Fumaroles and crater lake normal after earthquake

A VSI observer visited the volcano on 12 December. Fumaroles and the crater lake were normal and showed no evidence of increased activity that might be attributed to the M 6.5 earthquake of 26 November (preliminary epicenter 8.35°S, 124.25°E). The only notable change in the crater was a fresh landslide scar that may have resulted from the earthquake.

Steam clouds rise above a fumarole field on the flank of Gunung Sirung, south of Airmama village. The crater walls contain extensive areas of light-colored hydrothermally altered rock.

Sirung volcano, seen here from the north, 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 2-km-wide caldera at the summit has been the source of small phreatic eruptions during the 20th century. A lava dome (right) forms the 862-m-high summit of the volcano at the west side of the caldera.

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.

The summit of 862-m-high Gunung Sirung volcano on Pantar Island is truncated by a 2-km wide caldera whose floor often contains one or more small lakes. A number of small phreatic eruptions have taken place in the 20th century from vents inside the caldera.

Steam rises from a fumarole in the crater complex B, seen here from the NE. The summit of Gunung Sirung is cut by many craters and explosion pits, five of which contain lakes.

The Gunung Sirung volcanic massif rises to the south of the villages of Kaka and Mauta. The historically active cone is located at the NE end of a 14-km-long chain of volcanic centers that forms a peninsula extending south into the Sawu Sea. The light-colored area (right center) is a fumarole field near Airmama village. Gunung Sopak, the 1318 m high point of the massif, forms the peak at the upper right.
