On February 22, 2024 at 22:48 UTC, a magnitude 4.0 deep-focus earthquake struck 67 km ESE of Kumano, Japan, at a depth of 379.0 km and coordinates 33.6481°, 136.7858°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
