2024-10-23 19:03:05 UTC (2024-10-23) · approx. 3:03 PM UTC-4 local
On October 23, 2024 at 19:03 UTC, a magnitude 3.3 shallow crustal earthquake struck 68 km N of Charlotte Amalie, U.S. Virgin Islands, at a depth of 49.8 km and coordinates 18.9605°, -64.9557°.
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 120 m — a useful intuition for the size of the slip patch on the fault.
