On March 12, 2021 at 21:38 UTC, a magnitude 3.5 intermediate depth earthquake struck 66 km ENE of Punta Cana, Dominican Republic, at a depth of 106.0 km and coordinates 18.8198°, -67.8291°.

Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
