2026-08-09 06:35:33 UTC (6 hours ago) · approx. 2:35 AM UTC-4 local
On August 9, 2026 at 06:35 UTC, a magnitude 3.7 shallow crustal earthquake struck 132 km N of Charlotte Amalie, U.S. Virgin Islands, at a depth of 36.0 km and coordinates 19.5323°, -64.8290°.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 226 m — a useful intuition for the size of the slip patch on the fault.
