2021-12-21 22:58:48 UTC (2021-12-21) · approx. 5:58 PM UTC-5 local
On December 21, 2021 at 22:58 UTC, a magnitude 3.5 shallow crustal earthquake struck 121 km NE of Punta Cana, Dominican Republic, at a depth of 29.0 km and coordinates 19.4843°, -67.7510°.
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 145 m — a useful intuition for the size of the slip patch on the fault.
