“In Kamchatka, the eruption of the peak of the highest volcano in Eurasia, Klyuchevskoi, has begun. There are single discharges of volcanic bombs with a frequency of up to 10 explosions per hour. Scientists expect lava flows and mud flows that will pass along the riverbeds in the region of the volcano” , the announcement said.
The eruption started from the top of the crater. Due to the considerable depth of the volcano – about 200 meters, only individual ejecta are visible above the rim. Scientists warn that the intensity of the eruption will increase.
According to Alexei Ozerov, director of the institute, the eruptions of the Klyuchevskoi volcano can last from several weeks to a year.
The Klyuchevskoi volcano, whose height is 4800 meters, is the highest active volcano in Eurasia. Its age is estimated at 7000 years.
The last summit eruption was in early October 2020 and lasted until February 8, 2021.
