On July 23, 2026 at 18:15 UTC, a magnitude 3.5 shallow crustal earthquake struck 152 km NNE of Cruz Bay, U.S. Virgin Islands, at a depth of 37.0 km and coordinates 19.5998°, -64.2266°.

Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 3.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 167 m — a useful intuition for the size of the slip patch on the fault.
