On January 24, 2026 at 22:04 UTC, a magnitude 4.0 intermediate depth earthquake struck 25 km NNW of Shiranuka, Japan, at a depth of 134.3 km and coordinates 43.1839°, 144.0255°.

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.
