2026-09-29 00:55:42 UTC (37 min ago) · approx. 8:55 PM UTC-4 local
On September 29, 2026 at 00:55 UTC, a magnitude 3.3 shallow crustal earthquake struck 92 km NE of Cruz Bay, U.S. Virgin Islands, at a depth of 21.2 km and coordinates 18.9122°, -64.1583°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.5 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 122 m — a useful intuition for the size of the slip patch on the fault.
