2024-06-20 21:40:22 UTC (2024-06-20) · approx. 5:40 PM UTC-4 local
On June 20, 2024 at 21:40 UTC, a magnitude 3.2 shallow crustal earthquake struck 50 km N of Isabela, Puerto Rico, at a depth of 20.1 km and coordinates 18.9488°, -67.0955°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 985 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 99 m — a useful intuition for the size of the slip patch on the fault.
