Akhir 01, 1432 H/March 6, 2011, SPA -- A magnitude 6.2 earthquake jolted northern Chile on Sunday, the U.S. Geological Survey said, but there were no reports of any significant damage and the linchpin copper mining sector was not affected, according to Reuters. The quake struck about 67 miles (108 km) northeast of Arica, Chile, at a depth of 63 miles (101 km), it said. It originally reported the quake was magnitude 6.3. Local media reported some modest adobe homes in Chile's far north had been damaged, but there were no reports of any injuries. "There are no reports of any injuries or damage to infrastructure," a spokesman for state emergency office ONEMI told Reuters. "There were some small landslides onto roads in some areas in the north, but they were cleared without need for heavy machinery. No roads were damaged." State copper giant Codelco, the world's top producer, said it had not received any reports of damage to installations. And the world's No. 3 copper mine, Chile's Collahuasi, owned jointly by global miners Xstrata and Anglo American, said it was unaffected and was producing normally. Quake-prone Chile's economy is still recovering from a massive 8.8 magnitude earthquake a year ago, which hammered towns, infrastructure and industries in south-central Chile and killed more than 500 people.
