Massive 8.2 earthquake off Chile coast sparks tsunami --- (Reuters) - A major earthquake of magnitude 8.2 struck off the coast of Chile on Tuesday, leading to five deaths and triggering a tsunami that pounded the country's northern coast with 2-meter-tall waves. -- Officials said the dead included people who were crushed by collapsing walls or were killed by heart attacks. -- The U.S. Geological Survey said the quake was shallow at 12.5 miles below the seabed and struck about 100 km northwest of the mining port of Iquique near the Peruvian border. -- Mining in the world's No. 1 copper producer did not appear significantly interrupted, but about 300 prisoners took advantage of the emergency and escaped from a female penitentiary in Iquique. -- About 26 of the women were soon recaptured, authorities said, while security forces fanned out through the area amid reports of power outages and isolated looting. -- The Pacific Tsunami Warning Center said the quake generated a large tsunami with the biggest wave reported at about 2 meters. The Chilean navy said the first big wave hit the coast within 45 minutes. -- Iquique is a key port, close to Chile's main copper mines. The area has been on high alert in recent weeks after an unusual number of tremors, and a series of aftershocks further frayed nerves in the early hours of Wednesday. -- The city is more than 1,500 km north of Chile's capital Santiago, where the quake was not felt. - More, at: http://www.reuters.com/article/2014/04/02/us-chile-earthquake-idUSBREA3101G20140402
