(Getty Images) (Newser) – An earthquake has shaken down walls and knocked out electricity in parts of far-northern Chile. No injuries have been reported, though. The US Geological Survey calculates the magnitude as 6.2 and says it was centered about 41 miles east-northeast of Tacna, Peru, which is situated near Chile's border. The quake occurred at 6am ET. Tarapaca region Gov. Jose Durana says "walls have fallen in some sectors" and some roads were cut off. Many people in the northern town of Arica fled into the streets as the shaking started.
