On April 26, 2024 at 21:36 UTC, a magnitude 4.4 shallow crustal earthquake struck 29 km ENE of Hachinohe, Japan, at a depth of 66.7 km and coordinates 40.5970°, 141.8258°.
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.
