SANTIAGO - A 6.0 magnitude earthquake struck northern Chile on Saturday, the latest in a series of aftershocks to hit the mineral-rich Andean country since a powerful temblor.
The epicentre was 66km north-northwest of Antofagasta, Chile, the US Geological Service reported.
The quake, near the coast and Chile's border with Peru, struck just 7km below the surface, but Chilean and Peruvian media did not report any damages or injuries.
A Reuters witness said the aftershock was not felt hundreds of miles south in Santiago, the capital.
Earthquakes frequently strike Chile, where most residents live in valleys sandwiched between the Pacific Ocean and the Andes.
On Wednesday, a 7.7 magnitude earthquake near Antofagasta collapsed homes and large buildings, killing two people and injuring 115 others. A day later, on Thursday, two aftershocks with magnitudes of 6.2 and 6.8 hit northern Chile.
At least 15,000 people were left homeless by Wednesday's quake, which temporarily halted production at Chile's huge copper mines by cutting out power, the government has said.
