2025-07-23 20:01:31 UTC (2025-07-23) · approx. 7:01 AM UTC+11 local
On July 23, 2025 at 20:01 UTC, a magnitude 5.1 shallow crustal earthquake struck 117 km SE of Petropavlovsk-Kamchatsky, Russia, at a depth of 35.4 km and coordinates 52.4804°, 160.0866°. This earthquake was detected by 127 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.
