SAO PAULO A huge underground river appears to be flowing thousands of feet beneath the Amazon River, Brazilian scientists said Thursday.
Valiya Hamza of Brazil's National Observatory said researchers found indications the subterranean river is 3,700 miles (6,000 kilometers) long, about the same length as the Amazon on the surface.
He said the "thermal information" provided by Petrobras allowed his team of researchers to identify the movement of water 13,100 feet (4,000 meters) under the Amazon River.
Their findings were presented last week in Rio de Janeiro at a meeting of the Brazilian Geophysical Society.
