On December 9, 2022 at 19:04 UTC, a magnitude 4.4 deep-focus earthquake struck 176 km SSE of Alo, Wallis and Futuna, at a depth of 417.1 km and coordinates -15.8346°, -177.6298°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
