  1. Lake Nyos, Cameroon, 6.437N, 10.299E
    Maar Lake with dangerous CO2 levels, disasters in 1984 and 1986 killed many people. CO2 levels now controlled by self-siphon, which produces a self sustaining fountain.

  2. This is Lake Nyos in NW Cameroon, on the side of an active volcano, which regularly burped out masses of CO2 and killed people in the surrounding villages. Scientists now work to de-gas the lake floor so this doesn’t happen again, but there’s a risk that one side of the lake will collapse and flood the surrounding countryside.

  3. Lake Nyos in Cameroon where a release of carbon dioxide asphyxiated 1700 people in 1986. I actually found it by googling “carbon dioxide lake” after a few variations of contaminated lake, poisoned lake, etc.
