On March 24, 2025 at 23:19 UTC, a magnitude 4.3 shallow crustal earthquake struck 79 km ENE of Minami-Sōma, Japan, at a depth of 52.1 km and coordinates 37.7836°, 141.8557°.
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.
