2023-12-22 19:45:58 UTC (2023-12-22) · approx. 2:45 PM UTC-5 local
On December 22, 2023 at 19:45 UTC, a magnitude 4.0 shallow crustal earthquake struck 42 km NE of Miches, Dominican Republic, at a depth of 10.0 km and coordinates 19.2595°, -68.7638°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 13 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 320 m — a useful intuition for the size of the slip patch on the fault.
