Ash clouds, ash falls, pyroclastic flows, hot avalanches and lahars are a potential hazard associated with explosive eruptions of this volcano. The volcano poses a potential hazard to international and local airlines passing in the Kuriles region, since the height of its ash emissions can reach 10-15 km above sea level, ash plumes and clouds can drift hundreds and thousands of kilometers from the volcano in different directions.
