On July 26, 2026 at 14:16 UTC, a magnitude 4.2 deep-focus earthquake struck northwest of the Kuril Islands, at a depth of 493.8 km and coordinates 52.3485°, 152.2167°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
