The explosive eruption of the volcano continues.
According to the JMA local observatory, vulcanian-type explosion sent an ash column to 1,8 km height towards the southeast. Blocks were ejected 200 meters distance from the Ontake summit crater.
The volcanic-seismic tremor accompanied the event.
The warning bulletin states that ballistic impacts of volcanic bombs could affect an area of about 2 km distance from the main crater.
