On July 3, 2021 at 17:02 UTC, a magnitude 4.5 shallow crustal earthquake struck 245 km ESE of Tadine, New Caledonia, at a depth of 20.1 km and coordinates -22.2158°, 170.1472°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
