2024-01-11 09:50:08 UTC (2024-01-11) · approx. 9:50 PM UTC-12 local
On January 11, 2024 at 09:50 UTC, a magnitude 4.7 shallow crustal earthquake struck 104 km SSW of Alo, Wallis and Futuna, at a depth of 10.0 km and coordinates -15.2008°, -178.4270°. This earthquake was detected by 9 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
