M4.7 Earthquake in the Kermadec Islands region — February 19, 2024
2024-02-19 17:07:49 UTC (2024-02-19) · approx. 5:07 AM UTC-12 local
On February 19, 2024 at 17:07 UTC, a magnitude 4.7 deep-focus earthquake struck in the Kermadec Islands region, at a depth of 346.7 km and coordinates -29.3832°, -179.1168°. This earthquake was detected by 84 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
