On July 18, 2026 at 21:54 UTC, a magnitude 4.0 deep-focus earthquake struck 4 km NE of Mnogoudobnoye, Russia, at a depth of 502.7 km and coordinates 43.4944°, 132.5101°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
