On December 27, 2023 at 18:52 UTC, a magnitude 4.2 shallow crustal earthquake struck 114 km ENE of Petropavlovsk-Kamchatsky, Russia, at a depth of 62.0 km and coordinates 53.4551°, 160.2090°.
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.
