2025-05-31 18:37:11 UTC (2025-05-31) · approx. 2:37 PM UTC-4 local
On May 31, 2025 at 18:37 UTC, a magnitude 3.3 shallow crustal earthquake struck 49 km NNE of Cruz Bay, U.S. Virgin Islands, at a depth of 48.8 km and coordinates 18.7097°, -64.5500°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 116 m — a useful intuition for the size of the slip patch on the fault.
