On January 10, 2026 at 23:17 UTC, a magnitude 4.1 intermediate depth earthquake struck 36 km SSW of Makurazaki, Japan, at a depth of 154.4 km and coordinates 30.9799°, 130.1386°.

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.
