2025-11-04 03:58:16 UTC (2025-11-04) · approx. 2:58 PM UTC+11 local
On November 4, 2025 at 03:58 UTC, a magnitude 5.3 shallow crustal earthquake struck 142 km SE of Petropavlovsk-Kamchatsky, Russia, at a depth of 35.0 km and coordinates 52.2472°, 160.2458°. This earthquake was detected by 215 seismic stations with good location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
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.
