On July 23, 2025 at 19:25 UTC, a magnitude 4.1 shallow crustal earthquake struck 156 km E of Petropavlovsk-Kamchatsky, Russia, at a depth of 35.0 km and coordinates 53.2820°, 160.9343°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
