2023-10-13 23:32:24 UTC (2023-10-13) · approx. 7:32 PM UTC-4 local
On October 13, 2023 at 23:32 UTC, a magnitude 3.6 shallow crustal earthquake struck 60 km NNE of Cruz Bay, U.S. Virgin Islands, at a depth of 8.0 km and coordinates 18.8333°, -64.5560°.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 172 m — a useful intuition for the size of the slip patch on the fault.
