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

Ash plume from a small pyroclastic flow at Sinabung yesterdayNo 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.
As it slowly grows and advances, it continues to produce avalanches of rocks that break off its front and sides, which sometimes generate small to medium-sized pyroclastic flows with associated ash plumes that can rise to a few km.

An unusually large collapse of parts of the still active lava flow occurred last night at around 19:30 local time and produced a large, dangerous pyroclastic flow that traveled approx. 4.5 km to the SE. There are no reports of injuries or fatalities, hopefully because no one was in the affected part of the exclusion zone. The flow had stopped in the immediate vicinity of the evacuated villages Berastapu and Sukanalu. ... [more]

Weak lava extrusion continues to add material to the viscous lava lobe, which at the same time looses some of its mass in occasional small rockfalls from its front and the sides. These sometimes result in small pyroclastic flows. [more]

VAAC Darwin raised the Aviation Color Code to "Red" after a possible major ash plume was spotted on satellite imagery. According to the original report, a possible ash plume rose to estimated 50,000 ft (15 km) altitude 12:32 UTC on 22 May and drifted SW. The height was later reduced to 35,000 ft (12 km). ... [more]
