M4.3 Earthquake in the Kermadec Islands region — October 26, 2024
2024-10-26 21:21:58 UTC (2024-10-26) · approx. 9:21 AM UTC-12 local
On October 26, 2024 at 21:21 UTC, a magnitude 4.3 deep-focus earthquake struck in the Kermadec Islands region, at a depth of 400.4 km and coordinates -30.6207°, -179.5923°.
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.
