On November 21, 2022 at 22:25 UTC, a magnitude 5.1 shallow crustal earthquake struck 76 km S of Ust’-Kamchatsk Staryy, Russia, at a depth of 35.7 km and coordinates 55.5485°, 162.6418°. This earthquake was detected by 111 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.

The epicenter is located in Russia, a region characterized by the Kuril-Kamchatka subduction zone on the northwestern Pacific Ring of Fire. The nearest mapped fault system is the Kuril-Kamchatka Trench. View all earthquakes in Russia.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.1 earthquakes can continue for days to weeks and gradually diminish over time.

Has Russia had earthquakes this big before?

The largest recorded earthquake in Russia was the M9.0 Kamchatka earthquake of November 4, 1952. Today's magnitude 5.1 event is significantly smaller than that historical record.
