Underground river 'Rio Hamza' discovered 4km beneath the Amazon

Scientists estimate the subterranean river may be 6,000km long and hundreds of times wider than the Amazon

www.guardian.co.uk

"The Amazon flows much faster than the Hamza, however, draining a greater volume of water. Around 133,000m3 of water flow through the Amazon per second at speeds of up to 5 metres per second. The underground river's flow rate has been estimated at around 3,900m3 per second and it barely inches along at less than a millimetre per hour."

wow.

Holy...shit. What an amazing discovery! I never even considered underground rivers, I wonder what else is under our feet. How do you figure 100x the largest river on Earth? That's insane..
