On February 24, 2025 at 20:32 UTC, a magnitude 4.6 deep-focus earthquake struck 117 km SE of Alo, Wallis and Futuna, at a depth of 364.0 km and coordinates -15.0424°, -177.3179°. This earthquake was detected by 76 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
