A 6.2 magnitude earthquake struck Chile's mine rich north on Sunday, the US Geological Survey reported, but Chilean officials said there were no reports of any damage or injuries.

The quake was centered 49 miles (79 km) east northeast of Calama, at a depth of 61.5 miles (91 km). It hit at 20:11 local time (OO11 GMT).

"It was a quake of medium intensity. It caused some consternation among residents, but there are no reports of any damage," Johaziel Jamett, head of the early warning center at Chile's state emergency office Onemi, told Reuters.

An official at state copper giant Codelco, the world's top producer of the red metal, said there was no damage to the company's northern installations.

A huge 8.8 magnitude earthquake hit south-central Chile in February, killing at least 500 people and causing massive damage.
