Seismicity at Dempo volcano (PVMBG)
PVMBG raised the alert level of the volcano to 2 (waspada, "watch" on a scale of 1-4) because of increased seismic activity (mainly tremor and volcanic-tectonic earthquakes).
It is recommended not to approach the crater within 1 km.
The volcano's crater contains a large acid lake and a very active hydrothermal system. Phreatic or phreatomagmatic explosions could occur any time and would pose a significant risk.
The last eruptions in 2006 and 2009 were both phreatic.
