M5.1 Earthquake south of the Kermadec Islands — February 5, 2022
2022-02-05 17:47:49 UTC (2022-02-05) · approx. 5:47 AM UTC-12 local
On February 5, 2022 at 17:47 UTC, a magnitude 5.1 intermediate depth earthquake struck south of the Kermadec Islands, at a depth of 74.3 km and coordinates -33.1350°, -179.5560°.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
