On January 21, 2022 at 22:49 UTC, a magnitude 4.4 intermediate depth earthquake struck 47 km S of Mil’kovo, Russia, at a depth of 165.6 km and coordinates 54.2719°, 158.5455°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
