On August 10, 2025 at 20:01 UTC, a magnitude 4.2 shallow crustal earthquake struck 244 km SE of Petropavlovsk-Kamchatsky, Russia, at a depth of 10.0 km and coordinates 51.7735°, 161.5279°.
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.
