On September 28, 2022 at 21:48 UTC, a magnitude 4.2 intermediate depth earthquake struck 79 km SW of Kuril’sk, Russia, at a depth of 137.3 km and coordinates 44.7810°, 147.0931°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
