Activities present been in 2009 and most recently, August 21, 2023. Historical activity has been confined to being small-to-moderate explosive activity that produced ashfall near the volcano.

At 1:54 AM (GMT+7), a small phreatic explosion occurred causing small pyroclastic flows to ride down the northwest slope a few hundred meters downward, resulting to no injuries nor any damage to the surrounding landscape other than the volcano itself, lasting no more than 239s/3m59s.

The Royal Rotterdam Lloyd Dutch shipping company named and operated a fine passenger liner named 'Dempo' from 1931 to 1944 between Europe and South Asia.
