2020-06-12 21:03:30 UTC (2020-06-12) · approx. 5:03 PM UTC-4 local
On June 12, 2020 at 21:03 UTC, a magnitude 3.4 shallow crustal earthquake struck 35 km SSW of Charlotte Amalie, U.S. Virgin Islands, at a depth of 44.0 km and coordinates 18.0288°, -65.0200°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 2.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 140 m — a useful intuition for the size of the slip patch on the fault.
