The Most dangerous lake Lake Nyos in Cameroon is the most deadly lake in the world.
Lake Nyos in Cameroon is the most deadly lake in the world. No, it is not the large number of drowned people, it does not overflow the banks, and in it lives a terrible monster, devouring the locals. Located in the crater of a volcano that was considered dormant, its beauty Nios will not yield the picturesque lakes of Europe, Canada, USA and Japan.
Because of deep volcanic activity, which is still ongoing, carbon dioxide is constantly being raised through the pores in igneous rock. Meets with groundwater dissolves in them and with them falls into the lake. In the bottom layers of the lake accumulates a hell of a mixture, which does not mix with the upper layers.
Usually in crater lakes water is periodically stirred, aerated waters rise to the surface, and gases without harm to the natural environment are scattered in the atmosphere. But in Nyos and Monone the boundary between the layers is not disturbed. Gas continues to saturate the deeper layers of water until some external event will not disturb them. It can be strong wind and waves, unusually cold weather (when the upper layers of the water cool down and descend to a depth), landslide or earthquake.
Part of the deep water rises from the bottom, carbon dioxide is released from solution and bubbles rushes up, pulling even more bottom water. The inertia of the process increases rapidly a few bubbles turn into a gas stream, and finally from the open bottle of champagne, highly carbonated water fountain breaks up.
In 1986 in Nios like this “fountain hitting a height of 80 meters, and everything was drowned in a cloud of carbon dioxide. Heavy, twice as heavy as air, gas down on the lake shore and choked all life in its path. When in August 1984 exploded lake Monoun, 37 people were killed.
Lake Nyos is bigger and deeper, so deadly force would claim many more lives. The cloud of gas spreads around the neighborhood at a speed of over 70 kilometers per hour and quickly gets even to the villages located 20 kilometers away from the lake. The last one was killed by the explosion Nyos, a girl, the morning after the eruption came down the hill to the hollow, gas-filled.
