On April 11, 2024 at 15:55 UTC, a magnitude 4.1 deep-focus earthquake struck 270 km SE of Alo, Wallis and Futuna, at a depth of 382.1 km and coordinates -16.1078°, -176.4016°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
