Magnitude 8.0 quake off Chile sparks tsunami warning along Latin America's Pacific coast
"An earthquake of this size has the potential to generate a destructive tsunami that can strike coastlines near the epicentre within minutes and more distant coastlines within hours," it said.
The U.S. Geological Survey said the quake was very shallow, only 6.2 miles (10 km) below the seabed. It was cantered 53 miles (86 km) northwest of Iquique, CHILE (CHILE.CHL)(CHILE.CHL)(CHILE.84)s main mining export port.
