On August 18, 2024 at 15:58 UTC, a magnitude 3.4 shallow crustal earthquake struck 46 km N of Charlotte Amalie, U.S. Virgin Islands, at a depth of 53.7 km and coordinates 18.7645°, -64.9665°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 2.0 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 136 m — a useful intuition for the size of the slip patch on the fault.
