On January 20, 2026 at 23:29 UTC, a magnitude 4.9 shallow crustal earthquake struck 240 km ESE of Tadine, New Caledonia, at a depth of 10.0 km and coordinates -22.3517°, 170.0381°. This earthquake was detected by 38 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
