On December 21, 2024 at 17:08 UTC, a magnitude 4.0 intermediate depth earthquake struck 66 km ESE of Petropavlovsk-Kamchatsky, Russia, at a depth of 74.1 km and coordinates 52.9145°, 159.5846°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
