2025-04-15 22:29:37 UTC (2025-04-15) · approx. 6:29 PM UTC-4 local
On April 15, 2025 at 22:29 UTC, a magnitude 3.4 shallow crustal earthquake struck 99 km NNE of Cruz Bay, U.S. Virgin Islands, at a depth of 13.1 km and coordinates 19.1985°, -64.5338°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 129 m — a useful intuition for the size of the slip patch on the fault.
