On May 13, 2021 at 02:30 UTC, a magnitude 4.7 shallow crustal earthquake struck 251 km E of Tadine, New Caledonia, at a depth of 35.0 km and coordinates -21.8212°, 170.2917°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
