On October 17, 2020 at 23:23 UTC, a magnitude 4.4 shallow crustal earthquake struck 197 km ENE of Petropavlovsk-Kamchatsky, Russia, at a depth of 35.0 km and coordinates 53.6779°, 161.4285°.
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.
