The Silent Lake: The Physics and Tragedy of Lake Nyos
On twenty-one August nineteen eighty-six, Lake Nyos in Cameroon abruptly released a massive cloud of carbon dioxide that suffocated one thousand seven hundred and forty-six people in nearby valleys. Grounded in fluid dynamics and dissolved gas chemistry, this is the story of how an unseen geological hazard was uncovered and tamed.

A dense carbon dioxide cloud killed over seventeen hundred people across twenty-five kilometers in nineteen eighty-six.
Survivor skin blisters were actually hypoxia-induced pressure sores, not chemical burns.
Undisturbed lake sediments and pure carbon dioxide refuted early theories of a violent volcanic explosion.
Immense pressure at depth allowed one liter of lake water to hold ten liters of gas.
Self-siphoning pipes now vent gas into a fifty-meter geyser to prevent another runaway eruption.
