On August 26, 2025 at 22:31 UTC, a magnitude 4.3 shallow crustal earthquake struck 144 km E of Petropavlovsk-Kamchatsky, Russia, at a depth of 35.0 km and coordinates 53.0330°, 160.7813°.
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.
