On August 13, 2024 at 21:24 UTC, a magnitude 4.2 shallow crustal earthquake struck 124 km ENE of Hasaki, Japan, at a depth of 17.6 km and coordinates 36.2677°, 142.0473°.
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.
