On January 12, 2026 at 20:09 UTC, a magnitude 4.4 shallow crustal earthquake struck 39 km ENE of Anamizu, Japan, at a depth of 11.2 km and coordinates 37.4149°, 137.2779°.

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.
