To the list.
An English article describes a different danger of carbon dioxide and methane buried deeply at Lake Kivu in Africa.
"The gases are trapped in layers 80 metres below the lake's surface by the intense water pressures there. However, researchers have warned that geological or volcanic events could disturb these waters and release the gases.
"The impact would be devastating, as was demonstrated on 21 August 1986 at Lake Nyos in Cameroon, in West Africa. Its waters were saturated with carbon dioxide and a major disturbance - most probably a landslide - caused a huge cloud of carbon dioxide to bubble up from its depths and to pour down the valleys that lead from the crater lake.
"Carbon dioxide is denser than air, so that the 50mph cloud hugged the ground and smothered everything in its path. Some 1,700 people were suffocated."
