An increase in seismicity since 26 April triggered VSI to rise the alert status from 2 to 3 on a scale of 1-4 (from "Waspada," "watch" to Siaga," alert). For the moment, only degassing has been observed as surface activity. A similar increase in seismic activity was observed in Oct 2012, when the alert was raised as well and then reduced again in November. The last eruption at the volcano occurred in 2009. - Volcano Discovery
