On September 28, 2022 at 19:48 UTC, a magnitude 5.2 shallow crustal earthquake struck 22 km ENE of Codrington, Antigua and Barbuda, at a depth of 38.4 km and coordinates 17.7053°, -61.6358°. This earthquake was detected by 97 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 419, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
