CVGHM reported that seismicity at Sundoro continued to increase into January after the Alert Level was raised from 1 to 2 (on a scale of 1-4) on 5 December 2011. After the first week of January through 27 March the number of daily earthquakes significantly decreased. The Alert Level was lowered to 1 on 30 March.

Fumarolic and seismic activity in late 2011 results in brief rise in alert level

The last eruption reported for Sundoro volcano occurred 29 October 1971; however, that did not stimulate a resulting Bulletin report and this is our first on this volcano. According to Indonesian Center of Volcanology and Geological Hazard Mitigation (CVGHM), visual observations of Sundoro volcano during October - 4 December 2011 indicated 'smoke' from fumaroles around the summit crater. Average fumarole temperatures of 75°C on 26 October and 95°C on 2 November 2011 were measured. On November 2, the height of the 'smoke' had passed the rim of the volcano's crater. Seismic activity, especially volcanic earthquakes (deep volcanic tremors-VA, and shallow volcanic tremors-VB), began to increase in November 2011. On 5 December 2011, the Alert status (on a scale of I to IV) for Sundoro was raised from Normal (Level I) to Alert (Level II). Seismicity remained elevated through the first week of January 2012.

Throughout the rest of January, February, and through March 2012, a significant decrease of volcanic earthquakes (both VA and VB) was noted. Thus, the Alert status was lowered to Level I on 30 March 2012.

The area of Mt. Sundoro (also known as Sindoro; close to Mt. Sumbing) on Java (see figure 1 in BGVN 33:11), was the subject of a study of people's perceptions and reactions to volcanic hazards (Lavigne and others, 2008).

The symmetrical stratovolcano Sundoro, seen here from the NW with its flank vent of Gunung Kembang on the right, is one of two prominent stratovolcanoes SE of the Dieng volcanic complex in central Java. Explosive eruptions have occurred in historical time from both summit and flank vents.

Sundoro volcano, seen here from Wadas Putih village to its NW, is SE of the Dieng volcanic complex. Explosive eruptions have occurred from both summit and flank vents at during historical time, most recently in 1971.

A shallow lake is seen here on the floor of the K1 crater at the summit of Sundoro volcano in 1973. The 150-m-wide, 75-m-deep crater is seen here from the rim of the K2 crater immediately to the south.

Farmers cultivate land on the eastern flank of Gunung Sundoro in Java. The stratovolcano immediately NW of Sumbing volcano towers 2,500 m above its base. A small lava dome occupies the summit crater, which has fed lava flows in all directions. Historical eruptions typically have consisted of mild-to-moderate phreatic explosions, mostly from the summit crater, although flank vents were also active in 1882 and 1903.

Gunung Sundoro is located immediately NE of Sumbing volcano. The hill in the foreground is part of a large deposit resulting from a prehistoric debris avalanche that traveled around 20 km prior to formation of the present-day volcano. Explosive eruptions have occurred from both summit and flank vents in historical time.

Photo by Lee Siebert, 1995 (Smithsonian Institution).
The SE flank of Gunung Sundoro rises above fields to the west. Sundoro has erupted in historical time from both summit and flank vents and the cone at the lower left is Gunung Kembang.

An aerial view from the NW looks across the summit crater complex of Gunung Sundoro volcano towards Gunung Sumbing. These roughly 3,000-m-high volcanoes form prominent landmarks between the Dieng volcanic complex and the city of Yogyakarta. Both volcanoes have erupted in historical time.

The two small peaks to the left are part of the Telomoyo volcanic complex, which was constructed along a NNW-SSE-trending line of volcanoes extending from Ungaran in the N to Merapi in the S. Telomoyo filled much of the southern side of a depression formed by collapse of the Pleistocene Soropati volcano and grew to a height of 600 m above its rim. The two large peaks in the background are Sumbing (L) and Sundoro (R), with Slamet volcano on the far-right horizon.
