M5.1 Earthquake south of the Kermadec Islands — July 31, 2024
2024-07-31 14:54:14 UTC (2024-07-31) · approx. 2:54 AM UTC-12 local
On July 31, 2024 at 14:54 UTC, a magnitude 5.1 shallow crustal earthquake struck south of the Kermadec Islands, at a depth of 24.3 km and coordinates -33.7362°, -179.2513°. This earthquake was detected by 101 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
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.
