Posted on by Zena Henry

Guyana is on alert following a 7.6 magnitude earthquake that struck the Caribbean Sea, southwest of the Cayman Islands, at approximately 18:23 hours on Saturday.

An advisory from the Ministry of Home Affairs noted that while Guyana is not directly at risk due to its coastal location along the Atlantic Ocean, residents, especially those in low-lying and coastal areas, should remain vigilant.

Meanwhile, the Civil Defence Commission (CDC), National Drainage and Irrigation Authority (NDIA), Ministry of Public Works – Sea Defence, Guyana Police Force, and Community Policing Groups (CPGs) have been placed on high alert to monitor any potential developments.

The U.S. National Tsunami Warning Center initially issued tsunami watches for Puerto Rico and the Cayman Islands, but these have since been cancelled.

Despite this, local authorities continue to assess the situation and are advising residents to stay informed by following official updates, report any unusual coastal activity—such as sudden changes in water levels—and remain prepared for any unforeseen developments.

The situation is being closely monitored, and further updates will be provided as necessary, the advisory noted

CNN — An earthquake with a magnitude of 7.6 has occurred 129 miles southwest of Georgetown, Cayman Islands, according to the USGS.

The earthquake took place at 6.23 p.m. Eastern Time Saturday, the US Geological Survey (USGS) reported.

Based on all available data, there is a tsunami threat to Puerto Rico and the Virgin Islands as sea level fluctuations and strong ocean currents could be a hazard along coasts, beaches, in harbors and in coastal waters.

The generation of tsunami waves has not yet been confirmed, and the NTWC is monitoring to evaluate the tsunami threat.

Residents in Puerto Rico and the Virgin Islands are advised to move out of the water, off the beach and away from harbors, marinas, bays and inlets and not go to shore to observe the tsunami.
