On April 22, 2026 at 11:52 UTC, a magnitude 4.4 intermediate depth earthquake struck 31 km NE of Maketu, New Zealand, at a depth of 170.0 km and coordinates -37.5824°, 176.7272°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
