2022-01-15 20:43:07 UTC (2022-01-15) · approx. 4:43 PM UTC-4 local
On January 15, 2022 at 20:43 UTC, a magnitude 3.5 shallow crustal earthquake struck 85 km N of Cruz Bay, U.S. Virgin Islands, at a depth of 55.0 km and coordinates 19.1023°, -64.7410°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 3.2 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 170 m — a useful intuition for the size of the slip patch on the fault.
