SANTIAGO - A magnitude 6.2 earthquake struck off the northern coast of Chile on Friday, the US Geological Survey said, although there were no initial reports of damage.
The USGS said the quake's epicenter was located 18 miles below the seabed, 82 miles southwest of Antofagasta.
The quake, initially reported as a magnitude 6.0, struck at 6 p.m.
Local emergency services said the tremor was felt strongly in the northern Atacama desert, and they were assessing whether it had caused any damage. The navy said it was not issuing a tsunami alert.
A spokesman for Chilean state copper producer Codelco said there were no reports of any damage at its mines in the area.
