M4.5 Earthquake south of the Kermadec Islands — February 27, 2024
2024-02-27 21:44:14 UTC (2024-02-27) · approx. 9:44 AM UTC-12 local
On February 27, 2024 at 21:44 UTC, a magnitude 4.5 intermediate depth earthquake struck south of the Kermadec Islands, at a depth of 109.6 km and coordinates -32.8334°, -179.6007°. This earthquake was detected by 11 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
