On July 26, 2026 at 05:58 UTC, a magnitude 4.4 deep-focus earthquake struck 260 km N of Ama, Japan, at a depth of 446.1 km and coordinates 38.4173°, 133.4886°.
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.
