On May 2, 2023 at 20:34 UTC, a magnitude 4.4 shallow crustal earthquake struck 39 km ESE of Takahagi, Japan, at a depth of 45.3 km and coordinates 36.5894°, 141.1332°.
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.
