On July 4, 2022 at 07:27 UTC, a magnitude 5.2 deep-focus earthquake struck 165 km SSE of Alo, Wallis and Futuna, at a depth of 418.2 km and coordinates -15.7153°, -177.5751°. This earthquake was detected by 112 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
