Near-continuous explosions occur from the volcano's On-take summit crater. The Volcanic Ash Advisory Center Tokyo (VAAC) and the Japan Meteorological Agency reported about ash plumes which generally reached 6,000 ft-7,000 ft (1,828 m-2,133 m) altitude over the past days.
Explosions generated pyroclastic material such as ash, lapilli, bombs and blocks. Blocks were ejected 700 meters distance from the crater.
The volcanic-seismic tremor accompanied the explosive activity at the volcano.
The warning bulletin states that ballistic impacts of volcanic bombs could affect an area of about 2 km distance from the main crater.
