On June 18, 2026 at 08:32 UTC, a magnitude 4.1 shallow crustal earthquake struck 144 km NNE of Cruz Bay, U.S. Virgin Islands, at a depth of 52.0 km and coordinates 19.5758°, -64.3773°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 19 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 388 m — a useful intuition for the size of the slip patch on the fault.
