Exploding Lakes in Cameroon

In 1986, Lake Nyos, in the volcanic region of Cameroon, released a cloud of CO₂ into the atmosphere, killing 1,700 people and 3,500 livestock in nearby towns and villages. Since then, engineers have been artificially removing the gas from the lake through piping. A small CO₂ cloud from Lake Monoun killed 37 people in 1984.
