On August 16, 2024 at 18:34 UTC, a magnitude 4.2 deep-focus earthquake struck 257 km SSE of Alo, Wallis and Futuna, at a depth of 388.3 km and coordinates -16.5162°, -177.3459°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
