On July 5, 2026 at 23:22 UTC, a magnitude 3.9 deep-focus earthquake struck 294 km WNW of Ozernovskiy, Russia, at a depth of 535.1 km and coordinates 52.8014°, 152.7507°.

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.
