2024-02-13 22:57:18 UTC (2024-02-13) · approx. 6:57 PM UTC-4 local
On February 13, 2024 at 22:57 UTC, a magnitude 3.4 shallow crustal earthquake struck 143 km NNE of Cruz Bay, U.S. Virgin Islands, at a depth of 39.7 km and coordinates 19.5790°, -64.4395°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 2.0 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 136 m — a useful intuition for the size of the slip patch on the fault.
