On June 22, 2026 at 21:20 UTC, a magnitude 3.9 deep-focus earthquake struck 206 km NW of Kuril’sk, Russia, at a depth of 427.3 km and coordinates 46.7413°, 146.3374°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
