On October 26, 2026 at 04:12 UTC, a magnitude 4.2 shallow crustal earthquake struck 37 km E of Hachinohe, Japan, at a depth of 59.6 km and coordinates 40.5558°, 141.9305°.
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.
