On August 12, 2024 at 21:55 UTC, a magnitude 3.7 shallow crustal earthquake struck 119 km NE of Cruz Bay, U.S. Virgin Islands, at a depth of 22.0 km and coordinates 19.2163°, -64.1405°.0

Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 215 m — a useful intuition for the size of the slip patch on the fault.
