On November 18, 2022 at 11:41 UTC, a magnitude 5.0 shallow crustal earthquake struck 251 km ESE of Tadine, New Caledonia, at a depth of 10.0 km and coordinates -22.0518°, 170.2488°. This earthquake was detected by 48 seismic stations with good 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.
