On November 3, 2024 at 23:31 UTC, a magnitude 4.3 shallow crustal earthquake struck 5 km SE of Omigawa, Japan, at a depth of 62.3 km and coordinates 35.8121°, 140.6481°.

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.
