On April 9, 2022 at 19:11 UTC, a magnitude 4.2 intermediate depth earthquake struck 86 km SSW of Kuril’sk, Russia, at a depth of 113.4 km and coordinates 44.5211°, 147.4279°.
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.
