On February 3, 2026 at 22:14 UTC, a magnitude 4.2 intermediate depth earthquake struck 227 km WSW of Severo-Kuril’sk, Russia, at a depth of 225.4 km and coordinates 49.8257°, 153.2271°.

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.
