On November 26, 2025 at 22:06 UTC, a magnitude 4.3 intermediate depth earthquake struck 103 km N of Tarama, Japan, at a depth of 139.1 km and coordinates 25.6052°, 124.7524°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
