On September 8, 2024 at 23:03 UTC, a magnitude 3.4 shallow crustal earthquake struck 47 km N of Charlotte Amalie, U.S. Virgin Islands, at a depth of 69.1 km and coordinates 18.7688°, -64.8925°.

Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 129 m — a useful intuition for the size of the slip patch on the fault.
