On April 27, 2021 at 23:35 UTC, a magnitude 4.1 intermediate depth earthquake struck 100 km SSE of Atlasovo, Russia, at a depth of 115.4 km and coordinates 54.7739°, 160.2695°.
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.
