On September 11, 2025 at 16:31 UTC, a magnitude 4.4 shallow crustal earthquake struck 195 km SSW of Severo-Kuril’sk, Russia, at a depth of 60.6 km and coordinates 49.0208°, 155.2144°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
