On November 14, 2022 at 23:09 UTC, a magnitude 4.3 shallow crustal earthquake struck 106 km E of Namie, Japan, at a depth of 41.0 km and coordinates 37.6356°, 142.1862°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
