On September 14, 2025 at 17:28 UTC, a magnitude 4.3 shallow crustal earthquake struck 119 km ENE of Petropavlovsk-Kamchatsky, Russia, at a depth of 56.6 km and coordinates 53.5979°, 160.1821°.
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.
