Principal hazards are ash plumes, ash falls, lava and pyroclastic flows, hot avalanches. The volcanically dangerous zone threatened by lava and pyroclastic flows and hot avalanches will be limited to the caldera. A height of eruptive columns can reach 10 km a.s.l. but ash plumes are rising, mainly, up to 2.5-3 km a.s.l.
Activity of the volcano represents danger basically for local airlines.
Ash falls possible at settlements:
Milkovo (90 km to the north-west from the volcano)
Petropavlovsk-Kamchatsky (115 km to the south-south-east)
