On September 27, 2026 at 10:32 UTC, a magnitude 4.2 shallow crustal earthquake struck 4 km NNE of Mangatainoka, New Zealand, at a depth of 48.5 km and coordinates -40.3738°, 175.8819°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
