On December 2, 2021 at 21:01 UTC, a magnitude 4.4 intermediate depth earthquake struck 224 km ENE of Kuril’sk, Russia, at a depth of 94.7 km and coordinates 45.6557°, 150.6767°.
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.
