On May 25, 2026 at 21:49 UTC, a magnitude 4.3 shallow crustal earthquake struck 31 km WNW of Naha, Japan, at a depth of 39.4 km and coordinates 26.3404°, 127.3920°.
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.
