On September 1, 2026 at 23:24 UTC, a magnitude 4.3 shallow crustal earthquake struck 25 km ESE of Miyazaki, Japan, at a depth of 55.4 km and coordinates 31.8572°, 131.6819°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
