A 7.6-magnitude earthquake struck in the Caribbean Sea between the coast of Honduras and the Cayman Islands.
Tsunami warning centers said no tsunami waves had been confirmed but stress that people in Puerto Rico, other Caribbean islands and the coast of Central America should be alert to the danger of possible tsunami.
The U.S Geological Survey measured the quake at a preliminary magnitude of 7.6.
The tremor struck in the sea about 125 miles north-northeast of Barra Patuca, Honduras, and 188 miles southwest of George Town, Cayman Islands. The tremor occurred about 6 miles (10 kilometers) below the surface.
The northern coast of Honduras closest to the quake’s epicenter is sparsely populated, with much of it covered by nature reserves.
