2023-09-05 18:53:57 UTC (2023-09-05) · approx. 2:53 PM UTC-4 local
On September 5, 2023 at 18:53 UTC, a magnitude 3.6 shallow crustal earthquake struck 151 km N of Cruz Bay, U.S. Virgin Islands, at a depth of 30.0 km and coordinates 19.6821°, -64.5608°.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 187 m — a useful intuition for the size of the slip patch on the fault.
