Huge Underground River Below Amazon Found

chill writes: Researchers at the department of geophysics of the Brazil National Observatory have showed evidence of the existence of an underground river that flows 13,000 feet beneath the Amazon.

The width of the newly-named Hamza is said to be 3,700 miles long, flowing 13,000 feet below the Amazon. Both rivers flow from west to east, but the Hamza flows at only a fraction of the speed of Amazon.
