2022-06-24 23:09:38 UTC (2022-06-24) · approx. 7:09 PM UTC-4 local
On June 24, 2022 at 23:09 UTC, a magnitude 3.1 shallow crustal earthquake struck 96 km N of Brenas, Puerto Rico, at a depth of 32.5 km and coordinates 19.3385°, -66.3095°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 801 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 90 m — a useful intuition for the size of the slip patch on the fault.
