On August 15, 2025 at 03:13 UTC, a magnitude 4.8 shallow crustal earthquake struck 101 km NE of Tadine, New Caledonia, at a depth of 10.0 km and coordinates -20.7978°, 168.4491°. This earthquake was detected by 21 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
