Sinabung volcano (Sumatra): eruption news and activity updates
Sinabung volcano (Sumatra, Indonesia): possible major ash plume, but likely false report

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).

It is unclear if the plume was a volcanic ash plume, in which case it would suggest a major explosion occurred at the volcano. However, VSI and local media did not report any usual activity at the volcano, suggesting that most likely the observed plume was from a storm cloud.

Activity at the volcano remains weak. Slow lava extrusion continues along with occasional ash venting and small pyroclastic flows triggered by collapse of parts of the viscous lava lobe on the southern flank. ... read all

The volcano continues to slowly aliment the large viscous lava lobe on the SE flank. Its growth is mainly manifested by numerous small to medium-sized rockfalls from its flanks and front, but also occasional pyroclastic flows that have reappeared since mid April. ... read all

A pyroclastic flow occurred yesterday afternoon (17:40 WIB) at the volcano. Most likely, it was triggered by a partial collapse of the steep lava tongue that had been emplaced on its southern flank during the past months. read all
