Lake Monoun is a crater lake (maar) in West Province, Cameroon, that lies in the Oku Volcanic Field. On August 15, 1984, a limnic eruption occurred at the lake, which resulted in the release of a large amount of carbon dioxide (CO2) that killed 37 people. At first, the deaths remained unexplained, and causes such as terrorism were suspected. Further investigation and a similar event two years later at Lake Nyos led to the currently accepted explanation.[1]

Geochemistry Monograph Series. 1 (1): 1–50. doi:10.5047/gems.2017.00101.0001. Retrieved 2022-01-26. p. 7: Lake Monoun experienced a gas burst on 15 August 1984, that killed 37 people by asphyxiation. [..] It was found in a later survey that vegetation at the east end of the lake was flattened, indicating that the water wave locally reached up to 5 m high, and that the color of the lake water changed to a reddish brown.
