On September 5, 2026 at 18:46 UTC, a magnitude 3.9 shallow crustal earthquake struck 12 km NNE of Rahotu, New Zealand, at a depth of 10.6 km and coordinates -39.2201°, 173.8298°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
