2024-09-28 16:52:39 UTC (2024-09-28) · approx. 4:52 AM UTC-12 local
On September 28, 2024 at 16:52 UTC, a magnitude 5.1 shallow crustal earthquake struck 167 km SSW of Alo, Wallis and Futuna, at a depth of 10.0 km and coordinates -15.7267°, -178.6642°. This earthquake was detected by 100 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
