On November 7, 2022 at 19:41 UTC, a magnitude 4.4 shallow crustal earthquake struck 82 km ESE of Katsuren-haebaru, Japan, at a depth of 19.2 km and coordinates 26.1163°, 128.6638°.
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.
