SANTIAGO, Chile -An earthquake has rattled an area in northern Chile where the South American country's main mining operations are located.
The U.S. Geological Survey says the Sunday quake registered 6.2 magnitude and was centered about 50 miles (80 kilometers) east-northeast of Calama. That is 780 miles (1,260 kilometers) north-northeast of the Chilean capital of Santiago.
Chile's National Emergency Office says there were no reports of damage or injuries, but the quake caused alarm among residents and a brief interruption of telephone communications.
The tremor was hundreds of miles north of the region damaged by the 8.8-magnitude quake that struck south-central Chile on Feb. 27.
