M4.0 Earthquake in the Kermadec Islands region — December 30, 2024
2024-12-30 23:37:34 UTC (2024-12-30) · approx. 11:37 AM UTC-12 local
On December 30, 2024 at 23:37 UTC, a magnitude 4.0 intermediate depth earthquake struck in the Kermadec Islands region, at a depth of 202.0 km and coordinates -31.5828°, -179.7246°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
