On September 17, 2022 at 20:18 UTC, a magnitude 4.4 shallow crustal earthquake struck 51 km SSW of Ust’-Kamchatsk Staryy, Russia, at a depth of 55.1 km and coordinates 55.8002°, 162.1713°.
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.
