On July 29, 2026 at 20:16 UTC, a magnitude 4.4 shallow crustal earthquake struck 6 km WNW of Honmachi, Japan, at a depth of 11.7 km and coordinates 32.5324°, 130.5433°.

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.
