On November 22, 2025 at 18:54 UTC, a magnitude 4.1 intermediate depth earthquake struck 203 km SSW of Severo-Kuril’sk, Russia, at a depth of 80.2 km and coordinates 49.0189°, 154.9365°.

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.
