The Lake That Mysteriously Explodes: Killer Lakes of Africa

A Lake That Can Kill Without Warning

Deep in the heart of Africa lie some of the world’s most beautiful lakes — but a few of them hide deadly secrets beneath their calm surfaces.

In 1986, in a remote part of Cameroon, something terrifying happened at Lake Nyos. Without warning, 1,700 people and thousands of animals died overnight. The strange part? There was no sign of violence — just silence, and bodies.

The Invisible Killer: Carbon Dioxide

Lake Nyos is one of the world’s rare "exploding lakes." Over time, volcanic activity beneath the lake fills it with carbon dioxide gas. Normally, that gas stays trapped in the deep waters — until something triggers it, like a landslide or temperature change.

Then, all at once, the lake releases a massive cloud of CO₂, which suffocates every living thing in the area. It’s odorless, colorless, and heavier than air, so it creeps along the ground, silently stealing the oxygen from the air.

It’s Not the Only One

Lake Nyos isn’t alone. Lake Kivu, located on the border of Rwanda and the Democratic Republic of Congo, holds even more gas — enough to threaten millions of people if ever released. Scientists call it a "sleeping killer."
