2023-01-23 17:08:36 UTC (2023-01-23) · approx. 1:08 PM UTC-4 local
On January 23, 2023 at 17:08 UTC, a magnitude 3.2 shallow crustal earthquake struck 59 km NNE of Cruz Bay, U.S. Virgin Islands, at a depth of 11.0 km and coordinates 18.8482°, -64.6288°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 888 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 94 m — a useful intuition for the size of the slip patch on the fault.
