Volcanic lake gasesIn 1986, more than 1700 people died when toxic gas erupted from Lake Nyos, a volcanic lake in the West African nation of Cameroon. The gas was carbon dioxide which, being more dense than air, hugged the ground and flowed down valleys. The cloud travelled as far as 15 miles (25 km) from the lake. It was moving fast enough to flatten vegetation, including a few trees. In addition to the human deaths caused by suffocation, 845 people were hospitalized and 3,000 cattle died. Lake Nyos is a few square kilometres in area, and is around 200 m deep. It is situated in the crater formed from the collapse of the pipe feeding a now extinct volcano.
Don't marry Miss Green
I said to my father: "Dad, I want to get married."
He said: "Alright son, who do you want to marry?"
I said: "I'd like to marry Miss Green".
He said: "You can't".
I said: "Why not?"
He said: "She's your half-sister. When I was a lad I had a bike and I got around a bit."
I said: "Alright, I'll marry Miss White."
He said: "You can't, she's your half-sister. Forget about it."
Well, I was a bit despondent and I walked around and my mum said to me: "What's wrong with you?"
I said: "Well, I said to Dad I wanted to marry Miss Green and he said I couldn't because she's my half-sister. I said, "All right, I'll marry Miss White."
He said: 'You can't, she's your half-sister."
She said: "Look, you go and marry which one you like. He's not your father anyway!"
