Several eruption have occurred at the volcano during the past days, the volcano observatory reported.

The activity was not observed directly due to hazy conditions, but inferred from seismic signals. The eruptions are likely mild to moderate phreatic or phreatomagmatic explosive events from the crater lake, such as occasionally observed during the past months.
Some of the recent eruptive phases lasted unusually long, up to 9 hours. Ash plumes from the activity rose a few hundred meters.
Thermal signals (although weak) are frequently detected on satellite data, confirming that magma is near the surface at the volcano.
