M3.4 Earthquake in the Virgin Islands region — January 13, 2023
2023-01-13 17:03:31 UTC (2023-01-13) · approx. 1:03 PM UTC-4 local
On January 13, 2023 at 17:03 UTC, a magnitude 3.4 intermediate depth earthquake struck in the Virgin Islands region, at a depth of 83.9 km and coordinates 18.4198°, -64.8913°.
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.
