On March 25, 2025 at 21:00 UTC, a magnitude 4.1 intermediate depth earthquake struck 14 km ESE of Matamata, New Zealand, at a depth of 272.2 km and coordinates -37.8407°, 175.9243°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
