[edit intro]

Lake Kivu is one of the African Great Lakes. It is situated on Africa's Great Rift Valley and is one of these deepest lakes in the world.[1]

Due to its depth, surrounding climate, and underlying seismic activity, the Lake has a buildup of carbon dioxide, methane and sulfur dioxide.[1] Water in deep lakes in Temperate zones are mixed every year, when the lakes average temperature passes 4 degrees Celsius, the temperature at which water is most dense. Temperate lakes don't get gas buildup in their depths. Deep tropical lakes can get this build-up. And dissolved gas can build up for decades or centuries. When some event brings deep water saturated with gas to a level of the lake under less pressure the gas comes out of solution, like the gas in bottle of soda pop. This can trigger currents causing more mixing, and the discharge of the gas can become a runaway event.
