Increasing activity

Activity at the volcano remains elevated. Vertical explosions from the summit dome are relatively frequent and sometimes strong. This afternoon, an explosion generated an eruption column of approx. 2000 m above the summit.

The most recent phase of activity has been characterized by the destruction of the lava dome due to collapses, which have in turn resulted in frequent rockfalls and pyroclastic flows.

Larger than average pyroclastic flow claims at least 7 victims

A series of pyroclastic flows occurred in the afternoon of the 22nd of May - sadly, at least one of them was was much larger than most others during the past months, and claimed several fatalities among local farmers who were working on their fields within the exclusion zone, approx. 4 km from the volcano. The latest update includes 7 dead and at least 2 badly bunt among the victims. 

Beware of Mt. Sinabung, says National Disaster Mitigation Agency

The National Disaster Mitigation Agency (BNPB) heightened the alert status of Mount Sinabung in Karo regency, North Sumatra, on Wednesday after registering increasing volcanic activity.

The volume of hot lava spewing out of the mountain has reached 3 million cubic meters.

BNPB spokesperson Sutopo Purwo Nugroho said on Wednesday that with the increasing volcanic activity, the Sinabung had the potential to spew hot lava and ash clouds to the south and southeast as far as 7 kilometers from the crater.

Strong new eruption and large pyroclastic flow from Mount Sinabung

Indonesia's Mount Sinabung erupted early February 9, 2015 sending ash up to 4 km into the air. Aviation Color Code has been raised to Orange.

At 03:32 UTC today, plume was extending 31 km to the west, according to Darwin VAAC.

At 13:21 UTC, the agency reported volcanic ash is not identifiable on satellite imagery due to meteorological cloud and darkness, but is still expected in area.

Thick layers of volcanic ash after latest eruption of Mt. Sinabung, Indonesia

The eruption of Mount Sinabung on Saturday, January 3, 2015 halted activities in the districts of Tiganderket, Payung and Lau Balang. Pyroclastic flows reached as far as 4 km south of the volcano while the volcanic ash reached up to 3 km into the sky. 

According to The Jakarta Post, Saturday's three hour long eruption produced a total of 11 pyroclastic flows which affected the three districts located southwest of the volcano, completely covering the area with thick layers of volcanic ash. Thousands of residents were forced to flee their homes.

Strong eruption and major pyroclastic flow observed at Sinabung volcano, Indonesia

Darwin VAAC reported a high level eruption of Indonesian Sinabung volcano on December 14, 2014. Aviation Color Code was briefly set to Red and later downgraded to Orange as the eruption became less active.

At 02:32 UTC today (09:32 local time) volcanic ash cloud reached an altitude of approximately 6 km, and was extending 18 km to the NW.  Last high level erupting was observed at 03:40 UTC.

A large pyroclastic flow, approximately 4.5 km, was observed coming down the volcano yesterday.

New activity

Activity has picked up considerably at the volcano during the past days. Several pyroclastic flows (dangerous hot avalanches of fragmented lava and hot gasses) traveled down the SE (and some on the NE) flanks of the volcano, threatening again the closest inhabited areas to the S of Sinabung. The flows originated by collapses on the viscous growing lava lobe on the steep southeastern flank of the volcano and traveled distances of 3-4.5 km. Some still inhabited villages on the southern feet of the volcano are now at elevated risk.
