M4.1 Earthquake in the Kermadec Islands region — September 27, 2024
2024-09-27 22:05:50 UTC (2024-09-27) · approx. 10:05 AM UTC-12 local
On September 27, 2024 at 22:05 UTC, a magnitude 4.1 shallow crustal earthquake struck in the Kermadec Islands region, at a depth of 35.0 km and coordinates -31.6674°, -178.4887°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
