6.4 magnitude earthquake strikes northern ChileA 6.4-magnitude earthquake struck northern Chile today, and there was no immediate word of any injuries or damage. The earthquake struck at 1:51 a.m. local time – at a depth of 75 miles – about 30 miles southeast of Putre, near Chile’s border with Bolivia, according to the United States Geological Survey. Chile is one of the world’s most seismic countries and is prone to tsunamis because of the way the Nazca tectonic plate plunges beneath the South American plate, pushing the towering Andes cordillera ever higher.
