On July 15, 2026 at 12:38 UTC, a magnitude 4.4 shallow crustal earthquake struck 208 km SSE of Ust’-Kamchatsk Staryy, Russia, at a depth of 10.0 km and coordinates 54.6535°, 164.2703°.

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.
