An earthquake rattled Puerto Rico early Sunday, damaging houses in western and northern towns and causing a rock slide on a highway, according to The Associated Press (AP).

The magnitude-5.8 earthquake struck at 1:16 a.m. (0516 GMT) Sunday about four miles from the small community of Espino on the western side of the U.S. Caribbean island and 63 miles from the capital, San Juan, where it was felt by high-rise dwellers, according to the U.S. Geological Survey.

Melina Simeonides, a representative for Puerto Rico’s emergency management agency, said the quake also spilled rocks over a highway in Utuado, where it also shifted a concrete house four inches from its foundation.

Engineers and authorities were assessing the damage on Sunday.  No injuries have been reported.
