Overview

• Since erupting at 2:50 a.m. local time on August 4, the Krasheninnikov volcano has maintained moderate explosive activity with ash columns reaching up to 8.5 km.
• Ash plumes have drifted eastward over the open Pacific without affecting any settlements or depositing ash on inhabited areas.
• KVERT escalated to a red aviation alert nearly ten hours after the eruption began, warning of possible ash blasts to 10 km before returning to orange as activity eased.
• Tsunami warnings triggered by the recent 8.8 and 7.0 magnitude earthquakes have been canceled after no significant wave impacts were observed.
• The event is part of an unprecedented surge of unrest at six Kamchatka volcanoes, the largest cluster of simultaneous activity since 1737.
