On March 3, 2025 at 10:25 UTC, a magnitude 5.4 deep-focus earthquake struck 282 km SSE of Alo, Wallis and Futuna, at a depth of 413.7 km and coordinates -16.7565°, -177.3640°. This earthquake was detected by 124 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 449, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 km — a useful intuition for the size of the slip patch on the fault.
