On April 15, 2026 at 19:18 UTC, a magnitude 3.9 shallow crustal earthquake struck 36 km NE of Wanaka, New Zealand, at a depth of 14.4 km and coordinates -44.4445°, 169.4314°.

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.
