On September 15, 2025 at 16:09 UTC, a magnitude 4.4 shallow crustal earthquake struck 128 km ENE of Petropavlovsk-Kamchatsky, Russia, at a depth of 55.5 km and coordinates 53.4016°, 160.4736°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
