The activity of the volcano continues at elevated levels.
Moderate-to-strong vulcanian explosions are now in progress again at the volcano's On-take (Otake) NE summit crater. Similar activity occurred at the beginning of August as series of violent eruptions sent ash up to 3 km altitude.
A spectacular ash plume rising 8,500 ft (2,600 m) above the summit could be seen at about 09:10 local time today which spread northwest direction reported by Volcanic Ash Advisory Center (VAAC) Tokyo.
Explosions generated pyroclastic bombs and blocks ejected up to 400 meters away from the crater.
A near-constant glow is visible from the summit crater at night detected by surveillance cameras.
Short-term electronic tilt monitoring recorded a ground deformation on the western flank on 15 July.
The warning bulletin states that ballistic impacts of volcanic bombs could affect an area of about 1 km distance from the main crater.
