The Rwandan government has a plan to reduce the risk of a lake erupting while at the same time producing energy.
Deep below the surface of Lake Kivu lies a major threat to the two million people who live around the perimeter.
At the bottom of the lake are dissolved gases including 256 cubic kilometres of carbon dioxide and 65 cubic kilometres of methane, meaning the lake could explode if provoked, reports BBC.
Lake Kivu, which is partly in Rwanda and the Democratic Republic of Congo, is in a volcanic area and the CO2 enters the lake from the volcanic rock. The methane is created when bacteria in the lake mixes with CO2. The dangerous gases are kept at bay because they are deep below the surface and at high pressure, but if the lake is shaken, such as by an earthquake, the water would shoot upwards.
"Think of it like a bottle of fizzy drink," said Professor Brian Moss of the University of Liverpool to BBC. "The carbon dioxide has been dissolved in the drink. As long as it's underRead More »from Lake Kivu in Africa at risk of exploding from built up gases
