On June 10, 2025 at 18:14 UTC, a magnitude 4.2 intermediate depth earthquake struck 10 km W of Yanaizu, Japan, at a depth of 130.9 km and coordinates 37.5117°, 139.5985°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
