On March 28, 2026 at 19:34 UTC, a magnitude 3.4 intermediate depth earthquake struck 82 km ENE of Christiansted, U.S. Virgin Islands, at a depth of 139.6 km and coordinates 18.0485°, -63.9902°.

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.
