2020-08-05 21:35:19 UTC (2020-08-05) · approx. 9:35 AM UTC-12 local
On August 5, 2020 at 21:35 UTC, a magnitude 4.8 shallow crustal earthquake struck 269 km SSE of Alo, Wallis and Futuna, at a depth of 10.0 km and coordinates -16.6101°, -177.2809°.
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.
