An event mentioned in this article is an August 21 selected anniversary.
- "... a cloud of carbon dioxide gas suddenly boiled at Lake Nyos, ..."
- boiled is the wrong word, but I can't lay my hands on the right one for 'came out of solution' ...

[edit] Call for Clarification on Burns
The victims are reported in this article to have suffered "burns", which could not have been caused by C02 alone (unless it was very hot, which it doesn't seem to have been). The limnic eruption article mentions a theory that there was acid as well as C02 but suggests that this theory is not widely accepted, and doesn't mention the burns. Could someone clarify this please. Zargulon 14:15, 27 September 2005 (UTC)
- My understanding is that the victims were originally reported to have skin burns, but the reports were later clarified to describe "skin damage" such as discoloration.[1] Here's one explanation[2]:
- the skin lesions were in fact attributable to some combination of the following: (1) exposure to a direct heat source such as a cooking fire, (2) pressure sores from prolonged lying in a fixed position, (3) postmortem decomposition, and (4) sores that predated the event. Observed skin blisters were associated with extended unconsciousness, similar to symptoms found in comatose drug overdose patients.
- As far as I know there's no clear consensus, since that still doesn't explain the symptoms of the survivors, for example. Wmahan. 14:56, 27 September 2005 (UTC)
The skin burns to skin damage clarification in that source refers to a different limnic eruption, that of Lake Monoun. Are we sure that the survivors of lake Nyos are really supposed to have had burn symptoms? Zargulon 16:06, 27 September 2005 (UTC)
- You're right about the first link referring to Lake Monoun, but links like [3] appear to refer to Nyos: though these lesions were initially believed to be burns from acidic gases, further investigation suggested that they were associated with coma states caused by exposure to carbon dioxide in air.

Ok - thanks.Zargulon 16:32, 27 September 2005 (UTC)
[edit] degassing the lakes
Has any consideration ever been made towards using the pressure generated in the degassing process to generate electricity?
Could this electrical generation be used to offset the long term costs of adding more degassing pipes to these lakes?
I have been unable to find discussion on this topic. If you are aware of any papers or research towards this subject please post it.
- I can't answer your question, but you might also try asking at the Science Reference Desk. Hopefully, between here and there someone can at least hazard a guess. —BrianSmithson 02:36, 3 November 2005 (UTC)
[edit] biology
There must be rather interesting plants an possibly fish in there. Bacteria at least. Is anything known about that? 84.160.210.182 17:54, 4 December 2005 (UTC)
[edit] Weakening Dam
Engineers could also introduce a channel to allow excess water to drain; if the water level were lowered by about 20 metres, the pressure on the wall would be reduced significantly.
Would this not also have the effect of lowering the limnic eruption threshhold? -Antonius- 05:16, 11 December 2006 (UTC)
