2024-04-15 20:57:58 UTC (2024-04-15) · approx. 4:57 PM UTC-4 local
On April 15, 2024 at 20:57 UTC, a magnitude 3.8 shallow crustal earthquake struck 99 km N of Cruz Bay, U.S. Virgin Islands, at a depth of 23.0 km and coordinates 19.2211°, -64.6490°.
Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 244 m — a useful intuition for the size of the slip patch on the fault.
