On June 12, 2022 at 21:59 UTC, a magnitude 4.2 shallow crustal earthquake struck 188 km S of Ust’-Kamchatsk Staryy, Russia, at a depth of 35.0 km and coordinates 54.5487°, 162.0747°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
