Potencial Hazard

Potential hazards are caused by ash plumes, ash falls, lava and pyroclastic flows, hot avalanches and lahars.

The volcano constitutes a potential hazard to commercial aircrafts flying over Kamchatka and the Northern Kuriles because its eruptive clouds can rise to a height of 6-11 km a.s.l. and extend for hundreds of kilometers and the duration of eruptions can exeed a few months.

Ash falls possible at:

Severo-Kurilsk (60 km to the north-east from the volcano)
Ozernovskiy (145 km to the north-east)
