SANTIAGO, Jan 30 (Reuters) - A strong earthquake struck central-northern Chile on Wednesday, shaking buildings as far away as the capital, Santiago, but there were no immediate reports of damage or injuries, the U.S. Geological Survey (USGS) and local officials said.
The 6.7-magnitude quake struck at a depth of 29.5 miles (47.5 km), 63 miles (101 km) southwest of mining town Copiapo and 370 miles (596 km) north of capital Santiago, the USGS said.
It hit well south of where world No.1 copper producer Chile's massive metal deposits are located and Chile's emergency office said there were no preliminary reports of damage.
The navy said the quake did not meet the conditions needed to generate a tsunami off the country's Pacific coastline.
Nearly three years ago, a massive 8.8-magnitude earthquake and ensuing tsunami ravaged central-southern Chile, killing hundreds of people and causing billions of dollars worth of damage.
