The quake`s epicenter was 87 miles (139 km) northeast of the city of Salta, the U.S. Geological Survey said. It had a shallow depth of 5.9 miles (9.5 km), which raises the risk of damage.
"We haven`t had any reports of damage (but) the quake was felt strongly. People ran out onto the streets, they went running outside," a civil defense spokesman in Salta said.
Local media said the tremor was felt across much of northern Argentina. (*)
