2024-10-26 17:34:48 UTC (2024-10-26) · approx. 1:34 PM UTC-4 local
On October 26, 2024 at 17:34 UTC, a magnitude 3.8 shallow crustal earthquake struck 148 km NNE of Cruz Bay, U.S. Virgin Islands, at a depth of 30.0 km and coordinates 19.6426°, -64.4833°.
Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
