On March 3, 2023 at 20:39 UTC, a magnitude 4.2 intermediate depth earthquake struck 72 km NNE of Otrada, Russia, at a depth of 178.6 km and coordinates 44.6474°, 146.2709°.
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.
