Sinabung volcano (Sumatra): eruption news and activity updates
Sinabung volcano (Sumatra, Indonesia) activity update: continuing pyroclastic flows

Pyroclastic flow on Sinabung a few days ago
The eruption at the volcano continues. An expedition of our team is on location and observed near-continuous rockfalls and frequent pyroclastic flows caused by collapses on the lava flow reaching up to 4-5 km distance. The flows travel through two channels, on the south and to the north.

The increased phase of lava effusion and associated pyroclastic flows caused began about 2 weeks ago. VSI maintains alert level 3 (out of 4).
Seismic activity has been dominantly volcanic earthquakes and low-frequency quakes, representing magma pushing its way up to the surface, according to the volcano observatory.
Evacuation of the local people is still in process. Many inhabitants in endangered areas have moved to stay with other families in Berastagi or Medan city.

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. ...

Lava extrusion continues. A series of small to moderately sized pyroclastic flows occurred this morning at the volcano. The flows were likely produced as parts of the upper, unstable and still growing viscous lava dome on the SE flank collapsed: ... [more]

The volcano continues to slowly extrude viscous lava feeding the lava lobe on its southeastern flank. Occasional rockfalls, caused by instabilities on the steeper upper parts of the lava flows, continue to occur from time to time and represent a major hazard: Two larger ones occurred yesterday and produced pyroclastic flows that traveled 3.5 km distance to the southeast. ...

The volcano continues to slowly extrude lava feeding the large lava lobe on the southeastern flank. Occasional rockfalls and small pyroclastic flows have been observed in the past weeks. ... [more]

No significant changes in activity have occurred, although some local media reported apparently stronger (rock-fall and pyroclastic flow) activity over the weekend: The extrusion of viscous lava from the volcano's summit vent continues to feed the second lava lobe on the steep, upper SE slope of the volcano. ...
