On February 6, 2021 at 22:15 UTC, a magnitude 3.6 shallow crustal earthquake struck 80 km N of Charlotte Amalie, U.S. Virgin Islands, at a depth of 57.0 km and coordinates 19.0558°, -64.8050°.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 187 m — a useful intuition for the size of the slip patch on the fault.
