On December 12, 2023 at 17:03 UTC, a magnitude 4.4 deep-focus earthquake struck 262 km WNW of Ozernovskiy, Russia, at a depth of 436.6 km and coordinates 52.1157°, 152.8212°.
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.
