On March 12, 2025 at 02:45 UTC, a magnitude 4.7 shallow crustal earthquake struck 165 km E of Tadine, New Caledonia, at a depth of 10.0 km and coordinates -21.6192°, 169.4719°. This earthquake was detected by 56 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.
