THE VALLEY, Anguilla—An earthquake has shaken the tiny Caribbean island of Anguilla. There are no reports of injuries or damage.

The U.S. Geological Survey reports the quake's preliminary magnitude as 5.1 and says the epicenter was about 6 miles (10 kilometers) east-southeast of Anguilla's capital, The Valley. But it says the quake occurred far below the surface, about 55 miles (88 kilometers) down—a depth that tends to lessen the power of a tremor's shaking.

Police constable Terry Sylvester tells The Associated Press that it was the strongest earthquake he has ever felt but says residents have not reported any damage.
