On May 21, 2024 at 12:58 UTC, a magnitude 4.9 shallow crustal earthquake struck 276 km ESE of Tadine, New Caledonia, at a depth of 10.0 km and coordinates -22.3925°, 170.3995°. This earthquake was detected by 40 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.
