On June 16, 2025 at 15:56 UTC, a magnitude 3.1 shallow crustal earthquake struck 69 km N of Charlotte Amalie, U.S. Virgin Islands, at a depth of 22.1 km and coordinates 18.9618°, -65.0162°.

Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 629 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 80 m — a useful intuition for the size of the slip patch on the fault.
