On January 5, 2023 at 20:19 UTC, a magnitude 4.4 intermediate depth earthquake struck 153 km W of Naze, Japan, at a depth of 125.0 km and coordinates 28.1765°, 127.9378°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
