On May 25, 2024 at 21:03 UTC, a magnitude 4.3 shallow crustal earthquake struck 34 km NE of Opotiki, New Zealand, at a depth of 53.6 km and coordinates -37.7957°, 177.5670°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
