A strong earthquake struck northwestern Argentina on Saturday on the same day that a massive temblor struck neighboring Chile. Authorities reported at least one person was killed.
The 6.3 magnitude quake struck around midday about 15 miles north of the city of Salta, some 800 miles north-northwest of the capital Buenos Aires, the U.S. Geological Survey reported.
An 8-year-old boy died and two other children were injured, a hospital director in Salta told local media.
The quake was a separate event, not an aftershock of the devastating magnitude 8.8 quake that struck Chile, officials said.
The Geological Survey said the "triggered earthquake" was caused by ground waves from the Chilean temblor.
