On December 20, 2024 at 19:33 UTC, a magnitude 4.2 shallow crustal earthquake struck 157 km ESE of Atlasovo, Russia, at a depth of 44.5 km and coordinates 54.8464°, 161.7386°.
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.
