Kamchatka Records Five Aftershocks in a Day as Volcanic Unrest Continues

Overview

• Regional emergency services said five aftershocks from the July 30 Mw 8.8 quake were logged in the past 24 hours with magnitudes from 3.6 to 5.3, and one was felt.
• Over the past week, scientists recorded 12 felt events, including stronger shocks of magnitude 5.4 and 5.8 in reports covering population centers such as Petropavlovsk‑Kamchatsky.
• The Kamchatka segment of the subduction zone was reclassified to elevated background seismicity on November 12 following an earlier assessment of extremely high activity.
• Monitoring indicates activity at six volcanoes—Klyuchevskoy, Bezymianny, Shiveluch, Karymsky, Kambalny and Krasheninnikov—with an ash emission reported at Krasheninnikov and no ashfall in settlements.
• Authorities continue round‑the‑clock seismic and volcanic surveillance and advise residents that most aftershocks are not felt despite the ongoing sequence.
