The conditions for a Limnic Eruption
What happens
The gas rise up at 60mph out of the surface of the water. The animals and people soon start to feel the affects of the millions of cubic meters of CO2.
What happens
Examples
One example is Lake Nyos in Cameroon, Africa There was around 1,800 dead and over 3,00 dead livestock. The cloud went in a 25 kilometer radius.
Examples
How to prevent a Limnic Eruption
In Lake Nyos engineers have formed pipes that "de-gas" the bottom of the lake. The pipe brings up the CO 2 to the surface, making a cycle.
