2025-07-31 05:31:25 UTC (2025-07-31) · approx. 4:31 PM UTC+11 local
On July 31, 2025 at 05:31 UTC, a magnitude 5.6 shallow crustal earthquake struck 140 km ESE of Petropavlovsk-Kamchatsky, Russia, at a depth of 48.2 km and coordinates 52.6604°, 160.6055°. This earthquake was detected by 38 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 482, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.6 releases seismic energy equivalent to roughly 4 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 4.4 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.
