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

Small rockfall at the lava lobe of Sinabung a few days ago
The eruption continues with no significant changes, but on a progressively decreasing trend. Most activity has been the slow extrusion and gradual enlargement of the lava dome-lobe oozing out from the vent and onto the southern slope. Occasional rockfalls and minor pyroclastic flows occur as well.

As the intensity of the eruption decreases, refugees have been returning to their homes (except those from the closest villages at only 3 km distance).
A recent analysis of the erupted lava confirmed that the currently erupted lava is andesite (a viscous type of magma with intermediate silica content, and typical for volcanoes in subduction settings such as Sinabung and most other volcanoes in Indonesia).

The eruption of the volcano continues with little changes. During the past 2 days (see video below), there have been a number of smaller and occasional medium-sized explosions/dome collapse events that produced pyroclastic flows that reach up to 2-3 km length (at 13:50 yesterday and 07:50 this morning (local times). ...

Sad news today: the volcano claimed its first victims this morning due to a direct effect of the eruption. At least 14 people were reported killed and 3 others severely bunt by one or two moderately large pyroclastic flows this morning. 3 more people are still reported missing. ... [more]

The eruption shows little variations as the volcano continues to effuse viscous magma at the summit vent. A part of that simply contributes to the growth of the lava dome and the viscous lava tongue that descends on the SE flank. Another part of the new magma collapses and produces rock-falls that turn into pyroclastic flows such as this morning (video): ... [more]

Lava effusion continues at the volcano and pyroclastic flows occurred this morning. During the past 7-10 days, the growing lava dome has effused an impressive thick extrusion lobe that managed to form a massive, approx. 800 m long coherent lava flow reaching the base of the mountain. ... [more]
