In 2007 a group of brazilian geologists of the Coordenação de Geofísica do Observatório Nacional, guided by the Indian scientist Valiya Hamza discovered the world's longest underground river at a depth of 4 km under the Amazon river.
There is an enormous amount of water, flowing very slowly for 6000 km, from the Andes to the Atlantic Ocean. With a width between 100 and 200 kilometers, the river "Hamza" is probably the world's biggest groundwater. Hamza and his team analyzed datas coming from several oil wells dug by the Petrobras company, between 1970 and 1980.

The origins of this river is probably linked to the clash between the South-American plate and the one on which rests the Pacific Ocean. The peculiar porous and permeable rocks on the eastern ocean rim allow water to flow towards greater depths. Then impermeable layers block the rise of water and the topography gradient (the angle of the slope on which current flows) leads it to flow along the same direction of the Amazon River.
