Brazilian scientists say they have found signs of a huge underground river flowing far beneath the Amazon River, reports O Estado de Sao Paulo.
Valiya Hamza of Brazil’s National Geophysics Observatory says there are indications of a 6.000 kilometers long subterranean river located 4.000 meters below the surface.
The finding came from studying temperature variations at 241 inactive oil wells drilled in the 1970s and 1980s by Brazil’s state-run oil company Petrobras in search for hydrocarbons.
Hamza says the thermal information allowed his team of researchers to identify the movement of water under the Amazon River
The flow of the underground river which follows a similar contour to the Amazon has been estimated at 3.000 cubic meters per second.
This however is considered a mere 3% of the Amazon river flow which is born in the Peruvian jungle and empties in the Atlantic Ocean, to the extreme north of Brazil and is catalogued the longest in the world with 6.800 kilometers.
Hamza says the thermal information allowed his team of researchers to identify the movement of water 13,100 feet under the Amazon River.
Scientists agreed to name the underground river Hamza in honour of the Indian researcher Valiya Mannathal Hamza who has been studying the region for over four decades.
