The volcano had a new explosion from its crater lake last Wednesday 8 March. The eruption threw deposits of mud and ash onto the northern side of the crater to up to 120 m distance from the rim and generated a small plume of ash that caused light ash fall in nearby villages in up to 6 km distance to the north. ...more [read all]

The volcano increased its activity. Since 17 Sep, phreatic explosions have regularly occurred from the main crater which contains an acid lake. Although none was observed directly, at least 6 explosions could be identified by seismic signals. An aerial survey yesterday showed no fresh deposits, which suggests that the eruptions were rather small and did not eject material beyond the lake. ...more [read all]

The volcano has a very active hot lake whose degassing activity and temperature (48° C) increased after the magnitude 7.6 earthquake on 5 Sep. It has milky gray color due to mixing of sediments. ...more [read all]
