| Hazard synopsis |
Potential hazards are caused by ash plumes, ash falls, lava and pyroclastic flows, hot avalanches and lahars. The volcanic dangerous zone threatened by lava and pyroclastic flows, hot avalanches does not exceed 10 km from the volcano. Ash falls and lahars present potential hazard for Petropavlovsk-Kamchatsky, Yelizovo and other settlements situated close to the volcano.
Avachinsky volcano exposes potential hazard to the Kamchatkan airports and aircrafts flying over Kamchatka because its eruptive clouds can rise to a height up to 10-15 km above sea level and extend for hundreds of kilometers.
