2022-10-12 19:58:31 UTC (2022-10-12) · approx. 5:58 AM UTC+10 local
On October 12, 2022 at 19:58 UTC, a magnitude 4.1 intermediate depth earthquake struck 22 km NNE of Kuril’sk, Russia, at a depth of 171.5 km and coordinates 45.4188°, 147.9713°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
