M3.5 Earthquake 78 km E of Cruz Bay, U.S. Virgin Islands — October 16, 2022
2022-10-16 20:43:51 UTC (2022-10-16) · approx. 4:43 PM UTC-4 local
On October 16, 2022 at 20:43 UTC, a magnitude 3.5 shallow crustal earthquake struck 78 km E of Cruz Bay, U.S. Virgin Islands, at a depth of 44.0 km and coordinates 18.3415°, -64.0490°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.5 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 152 m — a useful intuition for the size of the slip patch on the fault.
