San Juan, PR – A strong earthquake struck near the Leeward Islands in the eastern Caribbean early Monday, prompting tsunami evaluations but no warnings for the United States or Gulf Coast regions.
According to the National Tsunami Warning Center (NTWC), the 6.8-magnitude quake was recorded at 8:39 a.m. EDT (1239 UTC) on October 27, 2025, approximately near Guadeloupe, in the Caribbean Sea. The quake occurred at a depth of about 6 miles (9 km).
The U.S. Geological Survey (USGS) later confirmed the event as a 6.5–6.8 magnitude earthquake, centered roughly 162 kilometers (100 miles) east of Beauséjour, Guadeloupe. The USGS assigned a “green” alert level, indicating little or no expected damage or casualties.
The NTWC emphasized that there is no tsunami danger for the U.S. East Coast, Gulf of Mexico, or eastern Canada. However, earthquakes of this magnitude can generate localized tsunamis near the source region, and Caribbean coastal residents were advised to monitor Pacific Tsunami Warning Center messages for updates.
No significant damage reports had been issued as of Monday morning, though mild shaking was felt across several islands, according to early “Did You Feel It?” responses.
Residents are encouraged to follow official updates via tsunami.gov for any changes to advisories.
