On June 23, 2026 at 21:53 UTC, a magnitude 4.5 deep-focus earthquake struck 269 km SSE of Alo, Wallis and Futuna, at a depth of 408.9 km and coordinates -16.5877°, -177.2188°. This earthquake was detected by 54 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
