2022-07-13 20:24:01 UTC (2022-07-13) · approx. 4:24 PM UTC-4 local
On July 13, 2022 at 20:24 UTC, a magnitude 3.7 shallow crustal earthquake struck 149 km N of Suárez, Puerto Rico, at a depth of 46.0 km and coordinates 19.7681°, -65.6286°.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 222 m — a useful intuition for the size of the slip patch on the fault.
