M4.8 Earthquake south of the Kermadec Islands — March 8, 2022
2022-03-08 05:26:39 UTC (2022-03-08) · approx. 5:26 PM UTC-12 local
On March 8, 2022 at 05:26 UTC, a magnitude 4.8 shallow crustal earthquake struck south of the Kermadec Islands, at a depth of 10.0 km and coordinates -33.4821°, -177.8961°.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
