6.7 quake hits western Brazil

A large but very deep 6.7 magnitude earthquake hit western Brazil Thursday, the US Geological Survey said.
The quake struck at 12:45, at a depth of 604km. It occurred some 50km southwest of the town of Tarauaca and 701km northeast of Lima, Peru.
The USGS had initially reported the quake's magnitude at 6.4.
No immediate reports of damage or casualties were reported after the temblor.

Deep South American earthquakes primarily occur in two zones: beneath the Peru-Brazil border,
where Thursday's quake hit, and also in an area running from central Bolivia to central Argentina, according to USGS.
