On November 3, 2025 at 21:49 UTC, a magnitude 4.3 shallow crustal earthquake struck 144 km SE of Petropavlovsk-Kamchatsky, Russia, at a depth of 10.0 km and coordinates 52.1915°, 160.2069°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
