Description

Krenitsin Peak volcano is located somewhat eccentrically in the northwestern part of Tao-Rushyr Caldera,. The volcano rises 900 m from the waters of the lake occupying the caldera. The diameter of the base of the volcano at the lake level is 3.5-4 km. The summit crater with a diameter of 350 m and a depth of up to 100 m is wide open to the southeast, turning into a deep pothole, reaching the shore of the lake. On the northwestern slope of the volcano there is a second pothole. On the northeastern slope of the volcano, at an altitude of about 900 m, there is an old lateral explosive crater with a diameter of 400-450 m. The volcano is named after the explorer of the Aleutian Islands, the head of the government expedition 1768-1770, captain First rank Peter Kuzmich Krenitsin [1-6].

Potencial Hazard
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.
