A gigantic underground river has been found thousands of feet below the world's second longest Amazon River, Brazilian Scientists discovered on Thursday.

Researchers from Brazil's National Observatory have found results indicating to a subterranean river 6,000 kilometers long, almost the same length as the Amazon directly above it, the Associated Press reported.

The information has come from 241 inactive oil wells drilled by the Brazilian oil company, Petrobras, according to Valiya Hamza, head of the research team from the observatory. Thermal information provided by Petrobras has allowed Hamza and his team to identify the movement of water 13,100 feet below the Amazon River.

The new findings suggest that the Amazon rainforest has two separate drainage systems, according to the Hamza who the new body of water has been named after.

Hamza has stated that the studies are still in their preliminary stage but he aims to confirm the subterranean flow of water by the end of 2014.

As the second largest river in the world, the South American Amazon River has the largest drainage basin in the world, approximately one-fifth of the world's entire river flow.
