2022-04-11 23:35:08 UTC (2022-04-11) · approx. 7:35 PM UTC-4 local
On April 11, 2022 at 23:35 UTC, a magnitude 3.1 shallow crustal earthquake struck 63 km N of Hatillo, Puerto Rico, at a depth of 30.5 km and coordinates 19.0587°, -66.8218°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 651 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 82 m — a useful intuition for the size of the slip patch on the fault.
