On April 28, 2024 at 12:23 UTC, a magnitude 4.9 shallow crustal earthquake struck 82 km N of Charlotte Amalie, U.S. Virgin Islands, at a depth of 10.0 km and coordinates 19.0875°, -64.8566°. This earthquake was detected by 27 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 380, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
