2025-03-16 18:17:07 UTC (2025-03-16) · approx. 2:17 PM UTC-4 local
On March 16, 2025 at 18:17 UTC, a magnitude 3.7 shallow crustal earthquake struck 147 km N of Charlotte Amalie, U.S. Virgin Islands, at a depth of 59.0 km and coordinates 19.6478°, -65.1930°.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 4.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 202 m — a useful intuition for the size of the slip patch on the fault.
