On October 17, 2020 at 15:51 UTC, a magnitude 4.2 intermediate depth earthquake struck 19 km ESE of Kozyrëvsk, Russia, at a depth of 151.3 km and coordinates 55.9594°, 160.1372°.
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.
