[00:00:00]On the night of August 21, 1986, villagers near Lake Nyos in Cameroon were asleep when disaster struck.

[00:00:09]Without warning, the lake released a massive cloud of carbon dioxide gas.

[00:00:14]The invisible cloud flowed silently through nearby valleys, displacing oxygen as it spread.

[00:00:21]People and animals lost consciousness within minutes.

[00:00:25]By morning, more than 1,700 people and thousands of livestock had died.

[00:00:32]Scientists later discovered that volcanic gases had been building up beneath the lake for years.

[00:00:38]A sudden disturbance triggered a rare phenomenon known as a limnic eruption.

[00:00:44]Today, special pipes continuously remove gas from the lake, helping prevent another catastrophe.

[00:00:51]It remains one of the strangest and deadliest natural disasters in modern history.
