There were a handful of survivors from each village after Lake Nyos overturned. How do you think they were able to survive this disaster? I need help I'm failing this class ​

Lake Nyos and the surrounding land in northwest Cameroon appear to be completely dead. There is no sign of birds or other animals.

The lake was the source of toxic gas 30 years ago that killed by suffocation some 2,000 people and 3,500 livestock animals within 25 kilometers of the lake. Magma under the lake leaks carbon dioxide into the water, and a large cloud of the deadly gas escaped into the air on August 21, 1986.

This camp situated 25 kilometers from the lake is now home to survivors.

Papa Saboum lost his 30-year-old wife at the time and still has fresh memories of what happened to him and his neighbor, a commissioner of police.
