Strombolian activity marked the Sinabung on 17 September, characterized by plumes of different colors, surmounting a nearby dome, always threatening the collapse.
The seismographs recorded three eruptions, and the observatory observed a column of ashes high of 1100 - 2000 meters, and some falls of ash on the Sinabung station.
Fears concern the Laborus River where a dam was formed upstream following pyroclastic flows. The PVMBG reports the formation of a lake that grows in size and could be responsible for a lahar or flash flood, following a collapse of this dam.
