On November 2, 2026 at 16:33 UTC, a magnitude 4.0 deep-focus earthquake struck 69 km NE of Makubetsu, Japan, at a depth of 330.0 km and coordinates 45.7897°, 142.4784°.

Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
