2026-07-02 04:18:55 UTC (2026-07-02) · approx. 12:18 AM UTC-4 local
On July 2, 2026 at 04:18 UTC, a magnitude 4.0 shallow crustal earthquake struck 140 km N of Cruz Bay, U.S. Virgin Islands, at a depth of 38.0 km and coordinates 19.5793°, -64.5750°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 17 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 369 m — a useful intuition for the size of the slip patch on the fault.
