On March 26, 2021 at 04:51 UTC, a magnitude 5.8 shallow crustal earthquake struck 65 km NE of Beauséjour, Guadeloupe, at a depth of 19.0 km and coordinates 16.7936°, -60.7286°. The earthquake was reported felt by 27 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.9 (light). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is Grande Anse (population 1,716).

Physical scale: An earthquake of magnitude 5.8 releases seismic energy equivalent to roughly 8 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 6.1 km — a useful intuition for the size of the slip patch on the fault.
