The explosive activity of the volcano continues characterized by near-constant eruptions.
A moderate-to-strong vulcanian-type explosion occurred at 06:41 local time yesterday as the Japan Meteorological Agency (JMA) noted. An ash plume rose to estimated altitude of 4 km and drifted SE as visible in the attached video. A lava bombs were ejected as far as 800 m away from the crater.
A strongly rising signal of volcanic tremor accompanied this event indicating rapid magma flux towards the surface. The seismic network detected 3 volcano-tectonic earthquakes yesterday.
Sulfur dioxide (SO2) emissions continue at high levels.
The warning bulletin states that ballistic impacts of volcanic bombs and pyroclastic flows could affect an area of about 2 km distance from the main crater.
