On April 11, 2026 at 20:04 UTC, a magnitude 4.4 shallow crustal earthquake struck 208 km SE of Taira, Japan, at a depth of 10.0 km and coordinates 25.3346°, 129.6564°.
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.
