2023-07-26 23:17:00 UTC (2023-07-26) · approx. 7:17 PM UTC-4 local
On July 26, 2023 at 23:17 UTC, a magnitude 3.2 intermediate depth earthquake struck 36 km ENE of Cruz Bay, U.S. Virgin Islands, at a depth of 73.8 km and coordinates 18.4588°, -64.4765°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
