2022-06-19 23:37:07 UTC (2022-06-19) · approx. 7:37 PM UTC-4 local
On June 19, 2022 at 23:37 UTC, a magnitude 3.7 shallow crustal earthquake struck 65 km N of Hatillo, Puerto Rico, at a depth of 36.0 km and coordinates 19.0806°, -66.8533°.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.0 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 209 m — a useful intuition for the size of the slip patch on the fault.
