2026-07-01 06:46:15 UTC (6 hours ago) · approx. 2:46 AM UTC-4 local
On July 1, 2026 at 06:46 UTC, a magnitude 3.4 shallow crustal earthquake struck 141 km NNE of Cruz Bay, U.S. Virgin Islands, at a depth of 55.4 km and coordinates 19.5563°, -64.4120°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 2.0 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 138 m — a useful intuition for the size of the slip patch on the fault.
