On November 22, 2025 at 17:37 UTC, a magnitude 4.3 shallow crustal earthquake struck 82 km ESE of Petropavlovsk-Kamchatsky, Russia, at a depth of 62.6 km and coordinates 52.7736°, 159.7536°.

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.
