On June 14, 2023 at 15:06 UTC, a magnitude 4.4 shallow crustal earthquake struck 7 km SE of Asahi, Japan, at a depth of 51.1 km and coordinates 35.6752°, 140.7184°.
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.
