2020-08-29 07:46:07 UTC (2020-08-29) · approx. 7:46 PM UTC-12 local
On August 29, 2020 at 07:46 UTC, a magnitude 5.2 shallow crustal earthquake struck 52 km SE of Alo, Wallis and Futuna, at a depth of 10.0 km and coordinates -14.6350°, -177.7578°.
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.
