On November 15, 2025 at 22:26 UTC, a magnitude 4.3 shallow crustal earthquake struck 74 km E of Noda, Japan, at a depth of 38.3 km and coordinates 40.2191°, 142.6795°.

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.
