M5.3 Earthquake 255 km ESE of Ust’-Kamchatsk Staryy, Russia — February 25, 2022
2022-02-25 13:48:42 UTC (2022-02-25) · approx. 12:48 AM UTC+11 local
Maximum shaking intensity MMI 4.0 (moderate).
On February 25, 2022 at 13:48 UTC, a magnitude 5.3 shallow crustal earthquake struck 255 km ESE of Ust’-Kamchatsk Staryy, Russia, at a depth of 27.8 km and coordinates 55.0024°, 165.8986°.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 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 5.3 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 5.3 event is significantly smaller than that historical record.
