On June 6, 2023 at 09:11 UTC, a magnitude 4.9 shallow crustal earthquake struck in the Haiti region, at a depth of 10.0 km and coordinates 18.6990°, -74.2301°. This earthquake was detected by 178 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 371, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
