IntroductionThere are no confirmed historic eruptions before the re-awakening in August 2010, but possibly it has had activity in around 1600 and 1881.
It is evident that Sinabung volcano has frequently erupted on its flanks producing lava flows. Sinabung has four overlapping summit craters, where fumaroles have been active, particularly in 1912, but no eruption followed the increase of fumarolic activity then. The 4 summit craters are aligned along a N-S direction. The youngest crater of this andesitic-to-dacitic volcano is at the southern end of the four overlapping summit craters.
