On July 19, 2026 at 19:29 UTC, a magnitude 4.3 intermediate depth earthquake struck 73 km ENE of Petropavlovsk-Kamchatsky, Russia, at a depth of 73.8 km and coordinates 53.2223°, 159.6936°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
