On December 3, 2022 at 18:29 UTC, a magnitude 4.1 intermediate depth earthquake struck 48 km NW of Shimokizukuri, Japan, at a depth of 163.3 km and coordinates 41.1549°, 140.0108°.
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.
