On December 13, 2021 at 11:44 UTC, a magnitude 5.3 shallow crustal earthquake struck 241 km E of Tadine, New Caledonia, at a depth of 24.7 km and coordinates -21.8145°, 170.1980°.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
