On June 15, 2026 at 19:21 UTC, a magnitude 4.4 shallow crustal earthquake struck 136 km E of Nishinoomote, Japan, at a depth of 13.8 km and coordinates 30.7088°, 132.4231°.
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.
