Shallow M6.5 earthquake hits offshore Guadeloupe
A shallow M6.5 earthquake was registered at 12:38 UTC on October 27, 2025, approximately 162 km (101 miles) east of Beauséjour, Guadeloupe. The earthquake occurred at a depth of 10.0 km (6.2 miles), with the epicenter located at coordinates 16.5°N, 59.6°W.
The epicenter is positioned offshore in the eastern Caribbean Sea, well east of the main island of Guadeloupe. The region features several inhabited islands with significant populations and falls within an active tectonic zone.
Given the proximity to the Guadeloupe archipelago, critical infrastructure such as regional seaports, airports, and inter-island transportation networks could be present nearby, potentially impacting travel and logistics.
There is no tsunami threat associated with this earthquake, based on its location and available data.
USGS issued a green alert for this event, indicating a low likelihood of casualties or damage. Maximum estimated shaking intensity reached IV, with 44 felt reports submitted. The significance index is 673 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.
Guadeloupe and surrounding Lesser Antilles islands are situated along the boundary between the Caribbean and North American plates, an area known for frequent seismic activity due to plate subduction and transform faulting.
