On May 6, 2023 at 23:19 UTC, a magnitude 4.1 shallow crustal earthquake struck 60 km SW of Ust’-Kamchatsk Staryy, Russia, at a depth of 69.3 km and coordinates 55.8609°, 161.7579°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
