7 Astonishing Things Seen By Humankind Only Once

The Lake Nyos accident

On the 21st of August, 1968, the Nyos Lake became a murderer. A huge amount of carbonic oxide was released into the air and a poisonous fog went down the mountain hill.As a result, over 1,700 people died as well as many animals and birds. The gas traveled a distance of 88,500 ft, leaving no chance for any living organism to survive.Scientists say that the reason this happened is most likely from huge amounts of gas from the bottom of the lake or from underwater volcanos. Today the lake and its gases are regularly drained out.
