On May 15, 2026 at 21:09 UTC, a magnitude 4.1 intermediate depth earthquake struck 105 km ENE of Petropavlovsk-Kamchatsky, Russia, at a depth of 74.1 km and coordinates 53.5372°, 160.0042°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
