A magnitude 6.7 earthquake hit the coast of north-central Chile on Saturday evening, the US Geological Survey said.
The quake struck at 10:32 p.m. local time (0132 GMT) about 15.6 km (9.7 miles) south-southwest of Coquimbo, the USGS said. The relatively shallow quake, just 53 km (33 miles) below the surface, rattled buildings in the capital city of Santiago.
The Pacific Tsunami Warning Center discarded a tsunami threat shortly after the tremor.
No initial damage or injuries have been reported, though there were sporadic reports of power outages near the epicenter of the quake.
