A strong, magnitude 6.6 quake hit central Chile on Saturday, shaking buildings and prompting power outages in the capital, Santiago, but not causing any major damage, according to Reuters. The epicenter was 31 miles (50 km) north-northeast of the port city of Valparaiso, the U.S. Geological Survey said. The quake, which the USGS originally reported at magnitude 6.3, hit at a depth of 20 miles (32 km). The Chilean navy said there was no tsunami risk. About 100,000 people in Santiago lost electricity, and there were also partial power cuts in the cities of Temuco and Valparaiso, said Chilean emergency service Onemi. There were no reports of any structural damage, Onemi said. Quakes are common in Chile, the world's top copper producer, and its infrastructure is designed to withstand strong tremors.
