A U.S. geological agency says two strong earthquakes struck deep below the surface in remote regions of Argentina and Brazil.
The U.S. Geological Survey says the first quake hit Brazil's western state of Amazonas Saturday, at about 9:30 a.m. local time (13:30 UTC). It measured 6.2 out of a possible 10 on the Richter scale, which measures the magnitude of earthquakes.
About three hours later, another quake shook the northern Jujuy region of Argentina, near the Bolivian border. That quake measured 6.1 on the Richter scale.
Both earthquakes occurred hundreds of kilometers underground, and there are no reports of damage.
