On May 26, 2025 at 19:18 UTC, a magnitude 4.5 intermediate depth earthquake struck in the Kermadec Islands region, at a depth of 77.9 km and coordinates -31.2474°, -178.8334°. This earthquake was detected by 20 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
