The Shiveluch volcano, situated on the Kamchatka Peninsula in Russia's Far East, erupted on Saturday, generating a substantial ash plume that reached 10 kilometers into the atmosphere. This eruption has triggered red-level aviation alerts for the area and surrounding regions due to the ash cloud extending 50 kilometers towards the Bering Sea. The Volcanology and Seismology Institute of the Far Eastern Branch of the Russian Academy of Sciences reported that a more powerful explosion could occur at any time, potentially sending ash as high as 12 kilometers. This recent activity marks the second eruption within a week, with the previous event occurring on Thursday, which produced an ash column of 8 kilometers. Shiveluch is one of Kamchatka's largest and most active volcanoes, located about 450 kilometers from the regional capital, Petropavlovsk-Kamchatsky, and 50 kilometers from the nearby settlement of Klyuchi. The last red-level alert associated with the volcano's activity was issued in 2024, indicating the ongoing volatility of this geological site.
