2020-11-08 22:57:47 UTC (2020-11-08) · approx. 6:57 PM UTC-4 local
On November 8, 2020 at 22:57 UTC, a magnitude 3.5 shallow crustal earthquake struck 132 km NNE of Suárez, Puerto Rico, at a depth of 31.0 km and coordinates 19.5916°, -65.5630°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 147 m — a useful intuition for the size of the slip patch on the fault.
