On January 31, 2024 at 11:12 UTC, a magnitude 4.7 shallow crustal earthquake struck 252 km ESE of Tadine, New Caledonia, at a depth of 25.8 km and coordinates -22.0496°, 170.2664°. This earthquake was detected by 24 seismic stations with good 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.
