On August 8, 2024 at 16:26 UTC, a magnitude 4.2 shallow crustal earthquake struck 14 km SE of Miyazaki, Japan, at a depth of 37.7 km and coordinates 31.8229°, 131.5260°.
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.
