M4.4 Earthquake south of the Kermadec Islands — July 14, 2025
2025-07-14 18:42:08 UTC (2025-07-14) · approx. 6:42 AM UTC-12 local
On July 14, 2025 at 18:42 UTC, a magnitude 4.4 shallow crustal earthquake struck south of the Kermadec Islands, at a depth of 10.0 km and coordinates -33.6042°, -178.6284°.
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.
