On November 14, 2025 at 11:50 UTC, a magnitude 4.1 shallow crustal earthquake struck 128 km E of Severo-Kuril’sk, Russia, at a depth of 35.0 km and coordinates 50.5132°, 157.9178°.

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.
