On July 12, 2026 at 02:39 UTC, a magnitude 4.4 intermediate depth earthquake struck 27 km NNW of Kushiro, Japan, at a depth of 123.5 km and coordinates 43.2128°, 144.2682°.

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.
