WASHINGTON (Reuters) - A 5.5 magnitude earthquake hit a copper-rich area of Chile on Monday, the U.S. Geological Survey said.
The epicenter of the quake was 94 miles southeast of Copiapo at a depth of 53.6 miles, the center said.
There were no immediate reports of casualties or damage.
Copiapo, about 500 miles north of Santiago, is the capital of a province of the same name. The area's economy depends on copper and silver mining, as well as agriculture.
