On January 23, 2024 at 20:42 UTC, a magnitude 4.2 shallow crustal earthquake struck 151 km ENE of Petropavlovsk-Kamchatsky, Russia, at a depth of 46.3 km and coordinates 53.5719°, 160.7313°.

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.
