2020-05-28 19:37:28 UTC (2020-05-28) · approx. 3:37 PM UTC-4 local
On May 28, 2020 at 19:37 UTC, a magnitude 3.0 shallow crustal earthquake struck 3 km S of Tallaboa, Puerto Rico, at a depth of 10.0 km and coordinates 17.9681°, -66.7201°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 430 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 67 m — a useful intuition for the size of the slip patch on the fault.
