On January 20, 2026 at 04:39 UTC, a magnitude 5.3 shallow crustal earthquake struck 250 km ESE of Tadine, New Caledonia, at a depth of 10.0 km and coordinates -22.4652°, 170.0983°. This earthquake was detected by 62 seismic stations with good location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
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.
