Felt by 1 person across nearby locations.
On July 31, 2025 at 20:36 UTC, a magnitude 5.7 shallow crustal earthquake struck 167 km ESE of Petropavlovsk-Kamchatsky, Russia, at a depth of 14.0 km and coordinates 52.5859°, 160.9806°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.7 (light). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 135 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 500, placing it among routine seismic activity. The nearest populated place is Paratunka (population 1,767).
Physical scale: An earthquake of magnitude 5.7 releases seismic energy equivalent to roughly 5 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 5.2 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 5.7 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 5.7 event is significantly smaller than that historical record.
