M4.3 Earthquake in the Kermadec Islands region — July 1, 2026
2026-07-01 19:56:45 UTC (2026-07-01) · approx. 7:56 AM UTC-12 local
On July 1, 2026 at 19:56 UTC, a magnitude 4.3 deep-focus earthquake struck in the Kermadec Islands region, at a depth of 442.6 km and coordinates -31.0629°, -179.9776°.
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.
