M5.0 Earthquake south of the Kermadec Islands — March 13, 2021
2021-03-13 06:00:09 UTC (2021-03-13) · approx. 6:00 PM UTC-12 local
On March 13, 2021 at 06:00 UTC, a magnitude 5.0 shallow crustal earthquake struck south of the Kermadec Islands, at a depth of 56.5 km and coordinates -34.4908°, -179.9500°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
