On November 29, 2022 at 20:22 UTC, a magnitude 3.1 shallow crustal earthquake struck 73 km NNW of Charlotte Amalie, U.S. Virgin Islands, at a depth of 20.2 km and coordinates 18.9755°, -65.1372°.

Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 773 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 88 m — a useful intuition for the size of the slip patch on the fault.
