Comments (3): Bracewell  2006-07-10 An excellent paper - thank you for your work. The Boston Globe came out with an article July 8, 2006 http://www.boston.com/news/world/europe/articles/2006/07/09/volcanic_leaks_point_to_climate_gas_storage_risks/ munira raji  2009-01-22 hello, Am doing a research project on lake Nyos,|What mechanism has been accepted and proved to have trigger the eruption in 1986? thank you Roman  2009-01-23 Roman 2009-01-23 Hello, Munira raji! Right after the disastrous surges of the gas from lake Nyos and Monoun, scientists supposed that by the trigger mechanism of catastrophe could be the heating of benthic waters of lakes by hot lava or could be the submarine explosion of volcano. However, such supposition had not confirmation by the facts. In future it is «Officially» accepted to consider that the concentration of solution of carbon dioxide in the waters of lake exceeded the possible limit, whereupon the external affecting on the waters of lake caused the catastrophic outburst of gas from lake. More than twenty years (after catastrophe), «official» researchers consider as plausible supposition that on the waters of lakes of Nyos and Monoun there could be such external affecting as landslides, mudslides, earthquakes, tidal wave, and the cool rain . However, there are not convincing proofs of landslides, mudslides, earthquakes, tidal wave, and the cool rain in the moment of catastrophe. Moreover, «official» supposition does not give proofs of intercommunication of catastrophes on the lakes of Nyos and Monoun. However, the mentioned «official» supposition is basis of projects of strengthening of the dam on the lake of Nyos ( Lake Nyos Dam Assessment, Cameron, September 2005, Joint UNEP/OCHAEnvironment Unit ) and is basis of projects of prevention of possible reiteration of catastrophes by degassing of waters of lakes. There is other, «unofficial» supposition about the trigger mechanism of the disastrous surges of the gas in an atmosphere from the lakes of Nyos and Monoun ( http://www.nyos.lv/). «Unofficial» supposition was not limited to only by the waters of lake. «Unofficial» supposition takes into account seepage of atmospheric precipitation (rain) into pressure aquifer, penetration of the concentrated solutions of carbon dioxide from magma into the pressure aquifer, the mixing (in the pressure aquifer) of the concentrated water solutions of carbon dioxide from magma with the atmospheric precipitation ( which was leaked out in pressure aquifer) and seepage in waters of lake (through soil under the bottom of lake) the water solution of carbon dioxide (which was appearing after mixing). At diminishing of amount of atmospheric precipitation the concentration of water solution is increased in pressure aquifer ( in soil under the bottom of lake) of . At exceeding of limit of concentration of carbon dioxide in water solutions (which are leaking into soil under the bottom of lake) the pressure of gaseous carbon dioxide increases in the gaseous micro bubbles, which be contained in soil. The increasing of pressure in the gaseous micro bubbles increases the pressure in soil under the bottom of lake. When the pressure in the soil under the bottom of lake will be exceeded against critical, the soil will be destructed and from the concentration water solutions of carbon dioxide (which was containing in the soil) will be surged the large volume of the gaseous carbon dioxide to the waters of lake. Gaseous carbon dioxide passes from soil in waters of lake and then will be thrown out in an atmosphere. The trigger mechanism of catastrophes on the lakes of Nyos and Monoun switched on by the diminishing of amount of atmospheric precipitations in the vicinities of lakes in spring and in summer in 1983. « Unofficial» supposition allows to explain intercommunication of catastrophes on the lakes of Nyos and Monoun, and also forecast time (at least for a year before ) of possible reiteration of catastrophes. name  E-mail
