SAN JUAN, Puerto Rico (AP) A magnitude 5.9 quake shook Puerto Rico on Saturday, causing further damage along the islands southern coast, where previous recent quakes have toppled homes and schools.

The U.S. Geological Survey said the 8:54 a.m. (1254 GMT) quake hit 8 miles (13 kilometers) southeast of Guanica at a shallow depth of 3 miles (5 kilometers).

Puerto Ricos Electric Power Authority said outages were reported across much of southern Puerto Rico and crews were assessing possible damage at power plants.

Brbara Cruz, a prosecutor who was in the southern coastal city of Ponce when the new quake hit, said concrete debris hit the sidewalk as buildings continued to crumble.

Everyone is out on the street, she said.

There were no immediate reports of injuries.
