The underground "river" flowing through the Amazon region is essentially a flow created by the movement of water from the ground through oil and gas exploration boreholes of Petrobras Brazil in the Amazon region, then flows. horizontally at a depth of several kilometers below the ground and forming a significant flow that we call the underground "river" , Valiya Hamza and Elizabeth Tavares Pimentel, working at the Brazilian National Observatory, said.

If this is a true underground river, it will be the longest underground river in the world with a total length of 6000 km.

The flow rate of the underground "river" is very slow, even slower than the speed of a glacier, but the water of this "river " is also very salty.

"Water and other liquids can actually flow through porous rocks but cannot reach the Atlantic Ocean because of being blocked by non-permeable sedimentary rocks," Jorge Figueiredo, Petrobras geologist, said. said.
