On September 19, 2026 at 12:07 UTC, a magnitude 4.4 shallow crustal earthquake struck 35 km NW of Ushibukamachi, Japan, at a depth of 10.0 km and coordinates 32.4207°, 129.7461°.
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.
