2020-06-30 19:57:03 UTC (2020-06-30) · approx. 3:57 PM UTC-4 local
On June 30, 2020 at 19:57 UTC, a magnitude 3.0 shallow crustal earthquake struck 7 km SSW of Indios, Puerto Rico, at a depth of 14.0 km and coordinates 17.9311°, -66.8386°.
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.
