On January 6, 2026 at 18:56 UTC, a magnitude 4.4 shallow crustal earthquake struck 24 km ESE of Ōfunato, Japan, at a depth of 65.1 km and coordinates 38.9612°, 141.9654°.

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.
