Story summary
- Engineers installed degassing pipes in Lake Nyos, Cameroon, to release trapped carbon dioxide and prevent eruptions.
- On August 21, 1986, Lake Nyos emitted a CO2 cloud that killed about 1,700 people and 3,500 livestock.
- Scientists say decades-long CO2 buildup, disturbed by a landslide, triggered the 1986 limnic eruption.
- Cameroon's Anglophone crisis since 2016 restricts access, delays reconstruction, and leaves locals fearful despite safety claims.
