On August 26, 2024 at 17:45 UTC, a magnitude 4.0 intermediate depth earthquake struck 28 km NE of Misawa, Japan, at a depth of 111.5 km and coordinates 40.8871°, 141.6000°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
