".. great efforts in degassing the lake ..." could not make the lake safe for the population. The main threat is hidden under the bottom of the lake. This threat from underground river, consisting of aqueous solution of CO2. In 1986, after the blast in the underground river below the bottom of the lake, killed more than 1,800 people, and 3,000 cattle and wildlife over a 25-km radius. Degassing in the lake has not eliminated the main source of the disaster in 1986. People need to know this. (http://nyos.lv/f/uploads/copy_of_article_new_translation__result.pdf )

Settlers need to know about it! Aim: "... remove the gas from these lakes" (Nyos and Monoun) "and make them safe." Successfully completed: "... remove the gas from these lakes" (degassing Nyos and Monoun) Is not satisfied and can not be accomplished by degassing lakes: "... make them safe." Under bottom of lake, under ground are flowing underground river, consisting of aqueous solutions of CO2. A layer of ground between bottom lake and between underground river it is analog of the cap on a bottle of soda. When the concentration of CO2 in the underground river rises, this are increasing the pressure on the layer of ground (a cap). When the pressure exceeds the strength of the layer of ground is an explosion with the release of CO2 into the atmosphere. It happened at Lake Nyos in 1986. Degassing of the lake can not prevent from disaster, which took place in 1986. Settlers need to know about it! (http://nyos.lv/en/nyos-30606 )
