Sinabung activity remains high, with on September 27th at least three eruptive episodes, accompanied by plumes of ash rising between 2,000 and 3,00 meters, interspersed with emission of a thick white degassing at 50-100 meters above the summit.

The dam on the River Laborus remains potentially dangerous, which can be the cause of lahar in case of rupture.
