On December 29, 2023 at 23:06 UTC, a magnitude 3.4 shallow crustal earthquake struck 70 km NNW of Charlotte Amalie, U.S. Virgin Islands, at a depth of 34.6 km and coordinates 18.9493°, -65.1253°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 2.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 140 m — a useful intuition for the size of the slip patch on the fault.
