Shallow M6.8 earthquake hits offshore Guadeloupe
An earthquake of magnitude M6.8 was recorded at 12:38 UTC on October 27, 2025, about 169 km (105 miles) east of Beauséjour, Guadeloupe. The quake struck at a shallow depth of 10.0 km (6.2 miles), based on the latest data from the US Geological Survey (USGS).
The coordinates for this earthquake place it offshore, east of the island of Guadeloupe in the Caribbean Sea, at approximately 16.5°N, 59.5°W. The event occurred in a region known for tectonic activity, situated between the Lesser Antilles island arc and the Atlantic Ocean.
Given its offshore location, this event was far from densely populated areas, but maritime infrastructure such as shipping lanes and possibly energy or communications cables may be present in the vicinity.
There is no tsunami threat associated with this earthquake, based on its location and available data.
One felt report has been filed for this event. The significance index is 712 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.
The Lesser Antilles region, including Guadeloupe, lies along the boundary between the North American and Caribbean plates, making it prone to significant seismic activity due to subduction and plate interactions.
