2021-02-08 19:23:18 UTC (2021-02-08) · approx. 3:23 PM UTC-4 local
On February 8, 2021 at 19:23 UTC, a magnitude 3.2 shallow crustal earthquake struck 65 km NNE of Cruz Bay, U.S. Virgin Islands, at a depth of 45.0 km and coordinates 18.9073°, -64.6588°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 985 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 99 m — a useful intuition for the size of the slip patch on the fault.
