On June 24, 2020 at 22:46 UTC, a magnitude 4.4 shallow crustal earthquake struck 75 km ESE of Hachinohe, Japan, at a depth of 55.9 km and coordinates 40.2815°, 142.3360°.
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.
