2021-02-19 03:10:30 UTC (2021-02-19) · approx. 3:10 PM UTC-12 local
On February 19, 2021 at 03:10 UTC, a magnitude 5.0 shallow crustal earthquake struck 126 km ESE of Alo, Wallis and Futuna, at a depth of 10.0 km and coordinates -14.6253°, -176.9814°.
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.
