On February 19, 2025 at 23:25 UTC, a magnitude 4.3 shallow crustal earthquake struck 53 km ESE of Ōfunato, Japan, at a depth of 66.6 km and coordinates 38.9216°, 142.3016°.

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.
