2025-08-23 19:37:48 UTC (2025-08-23) · approx. 3:37 PM UTC-4 local
On August 23, 2025 at 19:37 UTC, a magnitude 3.6 shallow crustal earthquake struck 105 km NNE of Cruz Bay, U.S. Virgin Islands, at a depth of 23.0 km and coordinates 19.2381°, -64.4996°.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 184 m — a useful intuition for the size of the slip patch on the fault.
