2020-07-19 17:17:42 UTC (2020-07-19) · approx. 1:17 PM UTC-4 local
On July 19, 2020 at 17:17 UTC, a magnitude 2.3 shallow crustal earthquake struck 3 km SE of La Parguera, Puerto Rico, at a depth of 6.0 km and coordinates 17.9511°, -67.0258°.
Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 42.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 23 m — a useful intuition for the size of the slip patch on the fault.
