Here is an interesting story about a natural disaster that occured in 1986 in Nyos, Cameroon. Apparently, a man was riding his bicycle when he saw several cattle dead, and so he walked to the nearby village to find out what had happened. When he got there, to his shock and dismay, everyone was dead. He decided to run and get help.
Apparently, when all was said and done, 1746 people, 3000 cattle, and virtually every wild animal in the area was dead. The other weird thing is that there was a lake nearby that had an old folklegend attached to it. Apparently, the legend said that evil spirits once rose out of the lake, and killed everyone living near the lake.
