On May 18, 2023 at 08:43 UTC, a magnitude 4.8 shallow crustal earthquake struck in the Dominican Republic region, at a depth of 15.3 km and coordinates 19.7455°, -70.7991°. This earthquake was detected by 161 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 411, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
