cloudJAPAN – A new eruption occurred yesterday at the volcano at 12h25 local time. It consisted of a single powerful explosion from the Shin-Dake crater. An ash plume rose to approx 1.5 km height, and a pyroclastic flow was generated. The eruption lasted about 10 minutes and much of the erupted mass collapsed into an impressive pyroclastic flow (hot avalanche of fragmented lava and gasses). There are no reports of victims or damage. Japanese volcanologists raised the alert level to 3 and closed access to the summit area.
