M3.6 Earthquake 114 km NNE of Cruz Bay, U.S. Virgin Islands — October 10, 2023
2023-10-10 23:59:05 UTC (2023-10-10) · approx. 7:59 PM UTC-4 local
On October 10, 2023 at 23:59 UTC, a magnitude 3.6 shallow crustal earthquake struck 114 km NNE of Cruz Bay, U.S. Virgin Islands, at a depth of 14.0 km and coordinates 19.2676°, -64.3425°.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 4.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 190 m — a useful intuition for the size of the slip patch on the fault.
