On October 17, 2026 at 04:19 UTC, a magnitude 4.8 deep-focus earthquake struck 196 km SSE of Alo, Wallis and Futuna, at a depth of 439.4 km and coordinates -16.0441°, -177.7283°. This earthquake was detected by 50 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
