A Limnic Eruption Causes A Lake To Explode
Limnic eruptions are also called lake overturns, and they occur due to a buildup of carbon dioxide in the deeper parts of a lake. When the lake is nearly saturated with the gas, a small event could trigger the eruption, sending large waves of water and millions of cubic meters of carbon dioxide into the air. Lake Monoun in Cameroon experienced a limnic eruption in 1984, followed by the nearby Lake Nyos in 1986.
Key Facts In This Video
The 1986 limnic eruption of Lake Nyos suffocated everything within a 25 km radius, killing more than 1,700 people. (0:11)
Most lakes don't experience limnic eruptions because their water circulates with yearly changes in temperature. (1:28)
Pipes were installed in Lake Nyos and Lake Monoun to allow the escape of carbon dioxide. (2:27)
