On April 26, 2026 at 19:53 UTC, a magnitude 4.4 shallow crustal earthquake struck 165 km ESE of Miyakojima, Japan, at a depth of 10.0 km and coordinates 24.0376°, 126.7176°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
