2021-01-16 19:46:33 UTC (2021-01-16) · approx. 2:46 PM UTC-5 local
On January 16, 2021 at 19:46 UTC, a magnitude 3.1 shallow crustal earthquake struck 65 km ENE of Punta Cana, Dominican Republic, at a depth of 67.0 km and coordinates 18.7316°, -67.8028°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 629 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 80 m — a useful intuition for the size of the slip patch on the fault.
