On December 3, 2022 at 22:21 UTC, a magnitude 4.2 shallow crustal earthquake struck 144 km ESE of Namie, Japan, at a depth of 27.6 km and coordinates 37.1377°, 142.5728°.
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.
