2023-07-10 21:32:15 UTC (2023-07-10) · approx. 5:32 PM UTC-4 local
On July 10, 2023 at 21:32 UTC, a magnitude 3.3 shallow crustal earthquake struck near Virgin Islands, at a depth of 15.5 km and coordinates 18.6538°, -64.0382°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 118 m — a useful intuition for the size of the slip patch on the fault.
