On August 27, 2025 at 18:45 UTC, a magnitude 4.2 shallow crustal earthquake struck 174 km SE of Petropavlovsk-Kamchatsky, Russia, at a depth of 42.8 km and coordinates 51.9585°, 160.4532°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
