On October 23, 2022 at 23:07 UTC, a magnitude 4.3 shallow crustal earthquake struck 50 km NNW of Tilichiki, Russia, at a depth of 10.0 km and coordinates 60.8158°, 165.5741°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
