On July 9, 2024 at 19:02 UTC, a magnitude 4.1 shallow crustal earthquake struck 32 km ESE of Ōfunato, Japan, at a depth of 60.6 km and coordinates 38.9391°, 142.0564°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
