On December 21, 2023 at 21:38 UTC, a magnitude 4.4 shallow crustal earthquake struck 88 km ENE of Tadine, New Caledonia, at a depth of 10.0 km and coordinates -21.1554°, 168.6292°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
