On May 21, 2024 at 21:40 UTC, a magnitude 4.4 intermediate depth earthquake struck 1 km N of Shisui, Japan, at a depth of 75.8 km and coordinates 35.7329°, 140.2705°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
