On May 24, 2026 at 06:08 UTC, a magnitude 4.2 intermediate depth earthquake struck 1 km NW of Hitachi-ota, Japan, at a depth of 80.2 km and coordinates 36.5576°, 140.5175°.

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.
