The latest activity at Klyuchevskoy and Bezymianny volcanoes in Kamchatka
The most intense paroxysmal stage of the eruption at Klyuchevsky volcano has ended. This update comes from RIA News, citing insights from Alexey Ozerov, who leads the Institute of Volcanology and Seismology within the Far Eastern Branch of the Russian Academy of Sciences. The region is closely monitoring ongoing seismic and gas emissions while assessing the aftermath of the recent explosive events.
Ozerov notes that the last time a similar paroxysmal burst occurred at Klyuchevskoy was in 1945, with the next crisis traced back to October 1, 1994. He explains that such intense phases typically last from six to ten hours before the activity subsides. This historical perspective helps scientists compare current observations with past eruptions and forecast potential shifts in behavior.
Since 1994, there has been a stretch with no equally strong eruption at Klyuchevskoye that persisted for over a decade. Presently, the volcano continues to emit ash plumes and volcanic gases to altitudes reaching approximately 11 kilometers above sea level, indicating persistent degassing and plume formation. The ongoing activity involves persistent steam, gas, and ash emissions as observed daily from mid-October onward.
Inclement effects near Kamchatka continue to unfold. Descending mudstone flows associated with eruptive activity have affected access on several roads, prompting temporary closures for safety. Authorities are actively coordinating cleanup operations, and traffic restrictions are scheduled to remain in place through the early evening hours of November 2.
Bezymianny and Klyuchevskaya Sopka remain active in eastern Kamchatka. Klyuchevskoy is widely recognized as the highest active volcano in Eurasia, with ongoing emissions of steam, volcanic gases, and ash. The latest observations indicate continued activity on a near-daily basis as of October 11. Nearby, the village of Klyuchi lies roughly 30 to 40 kilometers from Bezymyanny and Klyuchevskoy, home to about 4,500 residents who monitor conditions closely.
Earlier summaries highlighted a powerful ash plume from the Klyuchevskoy volcano reaching heights of up to 14 kilometers in some events. Observers and scientists emphasize the importance of remaining vigilant, given the potential for rapid changes in eruption dynamics and ash dispersion patterns affecting air traffic and local communities.
