On June 12, 2023 at 21:06 UTC, a magnitude 4.3 intermediate depth earthquake struck 96 km SSW of Ust’-Kamchatsk Staryy, Russia, at a depth of 71.8 km and coordinates 55.3939°, 162.0320°.
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.
