2024-09-14 19:05:17 UTC (2024-09-14) · approx. 3:05 PM UTC-4 local
On September 14, 2024 at 19:05 UTC, a magnitude 3.9 shallow crustal earthquake struck 156 km N of Cruz Bay, U.S. Virgin Islands, at a depth of 35.0 km and coordinates 19.7298°, -64.5918°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 10.0 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 287 m — a useful intuition for the size of the slip patch on the fault.
