Underground River 'Rio Hamza' Discovered 4km Beneath the Amazon
from the Guardian
Covering more than 7 million
square kilometres in South America,
the Amazon basin is one of the
biggest and most impressive river
systems in the world. But it turns
out we have only known half the
story until now.
Brazilian scientists have found a
new river in the Amazon
basin--around 4km underneath the
Amazon River. The Rio Hamza, named
after the head of the team of
researchers who found the
groundwater flow, appears to be as
long as the Amazon river but up to
hundreds of times wider.
Both the Amazon and Hamza flow
from west to east and are around the
same length, at 6,000km. But whereas
the Amazon ranges from 1km to 100km
in width, the Hamza ranges from
200km to 400km.
