The seismic activity of the volcano continues at fluctuating levels. No significant change has occurred since the last update.
On 28 and 29 June the Japan Meteorological Agency (JMA) recorded 4 and 2 volcano-tectonic earthquakes, respectively.
Emissions of gas and steam plume occurred that rose 656 ft (200 m) above the summit.
An eruption could occur with no warning.
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.
