M3.8 Earthquake in the Dominican Republic region — April 13, 2023
2023-04-13 16:20:30 UTC (2023-04-13) · approx. 11:20 AM UTC-5 local
On April 13, 2023 at 16:20 UTC, a magnitude 3.8 shallow crustal earthquake struck in the Dominican Republic region, at a depth of 5.0 km and coordinates 19.0650°, -68.2363°.
Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 8.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 260 m — a useful intuition for the size of the slip patch on the fault.
