M3.5 Earthquake 73 km N of Culebra, Puerto Rico — November 14, 2020
2020-11-14 19:41:50 UTC (2020-11-14) · approx. 3:41 PM UTC-4 local
On November 14, 2020 at 19:41 UTC, a magnitude 3.5 shallow crustal earthquake struck 73 km N of Culebra, Puerto Rico, at a depth of 29.0 km and coordinates 18.9610°, -65.1986°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.5 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 152 m — a useful intuition for the size of the slip patch on the fault.
