On November 11, 2020 at 22:05 UTC, a magnitude 3.3 intermediate depth earthquake struck 24 km S of Blowing Point Village, Anguilla, at a depth of 86.0 km and coordinates 17.9576°, -63.0983°.

Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
