On June 17, 2024 at 16:31 UTC, a magnitude 4.2 intermediate depth earthquake struck 35 km SSW of Urakawa, Japan, at a depth of 72.9 km and coordinates 41.8541°, 142.6474°.

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.
