On May 30, 2023 at 20:00 UTC, a magnitude 4.3 shallow crustal earthquake struck 82 km ESE of Petropavlovsk-Kamchatsky, Russia, at a depth of 51.5 km and coordinates 52.8456°, 159.7977°.
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.
