On February 14, 2021 at 22:52 UTC, a magnitude 4.6 shallow crustal earthquake struck 278 km ESE of Tadine, New Caledonia, at a depth of 10.0 km and coordinates -22.3982°, 170.4150°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
