Overview

• Krasheninnikov has maintained moderate explosive activity since August 3, with ash plumes rising up to six kilometers under an orange aviation alert.
• Ash clouds are drifting eastward over the Pacific without affecting any populated areas or causing recorded ashfall.
• Geophysicists from KVERT and Russia’s Academy of Sciences are evaluating stress changes from the July 29 magnitude-8.8 tremor to assess its role in ending the volcano’s six-century dormancy.
• Five other Kamchatka volcanoes—Avachinsky, Klyuchevskoy, Bezymianny, Kambalny and Karymsky—are erupting or showing unrest in the largest regional surge since 1737.
• Field teams near Klyuchevskoy reported the collapse of a dam on the Studenaya River, raising concerns about potential mudflows and local transport disruptions.
