2021-06-13 16:05:04 UTC (2021-06-13) · approx. 12:05 PM UTC-4 local
On June 13, 2021 at 16:05 UTC, a magnitude 3.4 shallow crustal earthquake struck near Virgin Islands, at a depth of 29.0 km and coordinates 18.7508°, -64.9011°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 125 m — a useful intuition for the size of the slip patch on the fault.
