On April 26, 2026 at 14:15 UTC, a magnitude 4.4 shallow crustal earthquake struck 100 km SSW of Severo-Kuril’sk, Russia, at a depth of 58.9 km and coordinates 49.8009°, 155.7585°.

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.
