On October 24, 2023 at 21:13 UTC, a magnitude 4.1 intermediate depth earthquake struck 163 km SW of Severo-Kuril’sk, Russia, at a depth of 126.7 km and coordinates 49.6002°, 154.5634°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
