On April 4, 2026 at 20:05 UTC, a magnitude 3.2 shallow crustal earthquake struck 54 km WSW of Saint Croix, U.S. Virgin Islands, at a depth of 12.2 km and coordinates 17.5832°, -65.2422°.

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 919 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 96 m — a useful intuition for the size of the slip patch on the fault.
