2020-06-17 18:36:41 UTC (2020-06-17) · approx. 2:36 PM UTC-4 local
On June 17, 2020 at 18:36 UTC, a magnitude 3.0 shallow crustal earthquake struck 5 km ESE of La Parguera, Puerto Rico, at a depth of 5.0 km and coordinates 17.9470°, -67.0028°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 494 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 72 m — a useful intuition for the size of the slip patch on the fault.
