On July 22, 2026 at 11:11 UTC, a magnitude 4.4 shallow crustal earthquake struck 58 km ESE of Tomioka, Japan, at a depth of 47.6 km and coordinates 37.2022°, 141.6529°.
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.
