2024-09-23 19:08:46 UTC (2024-09-23) · approx. 7:08 AM UTC+12 local
On September 23, 2024 at 19:08 UTC, a magnitude 5.0 intermediate depth earthquake struck south of the Kermadec Islands, at a depth of 194.6 km and coordinates -32.8176°, 179.8043°. This earthquake was detected by 59 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
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.
