2023-11-01 10:15:43 UTC (2023-11-01) · approx. 10:15 PM UTC-12 local
On November 1, 2023 at 10:15 UTC, a magnitude 5.0 deep-focus earthquake struck 144 km SSE of Alo, Wallis and Futuna, at a depth of 409.9 km and coordinates -15.5063°, -177.5648°. This earthquake was detected by 104 seismic stations with good location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
