M4.2 Earthquake in the Kermadec Islands region — October 17, 2024
2024-10-17 21:01:43 UTC (2024-10-17) · approx. 9:01 AM UTC-12 local
On October 17, 2024 at 21:01 UTC, a magnitude 4.2 intermediate depth earthquake struck in the Kermadec Islands region, at a depth of 246.0 km and coordinates -31.5844°, -179.8390°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
