On May 10, 2021 at 16:59 UTC, a magnitude 4.2 deep-focus earthquake struck 214 km NNW of Kuril’sk, Russia, at a depth of 343.5 km and coordinates 46.9813°, 146.7128°.
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.
