On November 21, 2022 at 21:06 UTC, a magnitude 4.1 shallow crustal earthquake struck 49 km SSW of Ust’-Kamchatsk Staryy, Russia, at a depth of 46.4 km and coordinates 55.7948°, 162.3042°.
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.
