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

The number of refugees to this day is as much as 25,810, from a total of 8,040 households, in 38 refugee camps. The lava dome seems to have decreased its activity, as no more significant pyroclastic flows occurred over the past 1-2 days. However, seismic activity remains high and it is too early to predict a near end of the eruption. It could even be a precursor to more violent explosive activity if the apparent calm at the moment is simply due to the fact that the degassing / effusion process in the past weeks has become inhibited by a plug of more viscous lava under which pressure is building up.
Another major hazard, especially with the likely heavy rains in the coming weeks, will be lahars - mud flows of remobilized loose ash. In addition to that, the up to 8-10 cm thick ash layer covering vast areas around the volcano is causing major damage and caused logistic difficulty (roads become muddy and impracticable).

Activity at the volcano remains unchanged. Eruptions with frequent small to medium-sized pyroclastic flows (up to 4-5 km length) continue and more than 25,000 people are reported evacuated. Problems caused by the extensive damage to crops and structures, health and infrastructure problems caused by the ongoing crisis with ash everywhere are increasing. ... [more]

The volcano continues to be very active with viscous lava extruded at the new dome, which frequently collapses to form hot avalanches (pyroclastic flows) that generate ash plumes rising up to a few km. ... [more]

Activity of the volcano has remained similar to the previous days. The actively growing lava dome, being a mass of unstable, moderately viscous lava, frequently collapses in parts and produces hot bloack and ash avalanches (pyroclastic flows) that reached up to 4.5 km distance. According to the latest figures, the number of refugees from the 5-7 km exclusion zone has reached approx. 25,000. [more]

The volcano's eruption remains essentially stable. The volcano continues to produce frequent pyroclastic flows - avalanches of lava rocks and ash mixed with gas and air, triggered by partial collapses of the growing lava dome. They continue to reach 2-4 km lengths and run down the SE slope where an extensive delta of pyroclastic deposits is formed. ... [more]

The activity of the volcano has remained similar with frequent, fortunately only small to medium sized pyroclastic flows and associated ash plumes. [more]
