2021-12-09 22:53:08 UTC (2021-12-09) · approx. 6:53 PM UTC-4 local
On December 9, 2021 at 22:53 UTC, a magnitude 2.0 shallow crustal earthquake struck 3 km SSE of La Parguera, Puerto Rico, at a depth of 13.0 km and coordinates 17.9451°, -67.0286°.
Physical scale: An earthquake of magnitude 2.0 releases seismic energy equivalent to roughly 17.9 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 16 m — a useful intuition for the size of the slip patch on the fault.
