On November 14, 2026 at 07:24 UTC, a magnitude 4.1 deep-focus earthquake struck southeast of Shikoku, Japan, at a depth of 506.9 km and coordinates 30.0796°, 136.9461°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
