2024-10-18 16:37:28 UTC (2024-10-18) · approx. 12:37 PM UTC-4 local
On October 18, 2024 at 16:37 UTC, a magnitude 3.4 shallow crustal earthquake struck 130 km NNE of Vieques, Puerto Rico, at a depth of 64.1 km and coordinates 19.5437°, -65.4308°.
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 127 m — a useful intuition for the size of the slip patch on the fault.
