On February 2, 2026 at 21:58 UTC, a magnitude 4.3 shallow crustal earthquake struck 125 km E of Namie, Japan, at a depth of 35.0 km and coordinates 37.5830°, 142.4091°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
