An earthquake using a preliminary magnitude of 5.7 struck the Caribbean island of Puerto Rico early Sunday, the U.S. Geological Survey stated.
The quake hit at 1:16 a.m. (0516 GMT) four miles (six kilometers) in the little community of Espino about the western side from the island and 63 miles (101 kilometers) in the capital, San Juan. It was recorded at a depth of 68 miles (110 kilometers).
There had been no immediate reports of injuries or harm. The West Coast and Alaska Tsunami Warning Center mentioned it did not assume a tsunami, but nearby tsunamis triggered by underwater landslides have been feasible in coastal places close to the epicenter.
