On October 17, 2025 at 17:57 UTC, a magnitude 4.4 shallow crustal earthquake struck 106 km ENE of Petropavlovsk-Kamchatsky, Russia, at a depth of 66.2 km and coordinates 53.4484°, 160.0918°.

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.
