lakes that kills thousands of lives

This lake has been Swallowing Death Toll 1800 - Odd News, Lake Nyos is located in al Cameroon, West Africa, until now still save a million mystery in it. The lake area has a depth of 157m with the deepest achive 208m was known haunted. There are many people living in the valley around the lake. This lake is so scary store histori precisely in 1986, there have been a strange event in the settlement. Around 1,700 people have died suddenly and simultaneously. 

Even more strangely, all residents were killed in a position while performing their daily work. There are as pumping water, cooking, and some are killed while drinking water. Some survivors of the event tells the tragic story. He said, the night before the incident, suddenly the air was warm and smelled like rotten eggs. The community is not too concerned about it. And suddenly the next morning, a lot of corpses when getting busy with their daily activities. 

No one knows for sure what caused the strange death. But the experts found that the color of the water of Lake Nyos changed from clear to bright orange color. To search for an answer, the experts then examined Craten Lake in Oregon. This lake is the largest lake in the world number seven. The extent of 50 square kilometers with a depth of 594 meters. So described if the Empire State entered into this lake, it will sink. 

Craten lake holds about 19 trillion liters of water. Approximately 7700 years ago, Mount Mazame the place erupted and threw the top of the mountain. Crater Lake is then formed Craten. However, it remains Mazame volcanic activity affecting the lake. Because under the lake was still there the former magma pools are still hot. The experts found that the water temperature at the bottom of the lake a few degrees warmer, the salt content is also ten times more concentrated and contains a lot of CO2. And CO2 is then seeped from the crevices of the earth's crust and into the crater that has now become a lake. 

However, the presence of water has prevented the rise of CO2 into the air. Even if there is a little loose, still carried by the wind can be lost. So it is not too dangerous. The process also greatly affect the change of seasons. In winter, the velocity of the water will be pushed down because of warmer temperatures below. Conversely in the summer, the velocity of the water will rise to the top. 

The cycle is then made the emergence of the water layers of different density levels. The lowest layer of water is more concentrated than the above. In the bottom layer of water that is flowing from the bottom of the CO2 retained earth. CO2 can not rise higher because of differences in water density in the layer above it. So gathered and accumulated over decades and become very much in the bottom water layer. 

This phenomenon was later found also in Horseshoe Lake is smaller than Lake Craten. The trees that grow around the lake dries up and eventually die. After investigation, it turns out CO2 levels in the lake is up to 100 tons / day and soak into the ground. This is what makes the trees around them die. The experts then conduct experiments to dig a little dirt on the lake and tried to light a fire. 

However, due to its pekatnya CO2 levels, the fire was extinguished immediately brought closer to the ground. It turned out that the accumulation of CO2 that has been very much on the lake finally overflowed and caused the lake to be very dangerous. However, CO2 levels at Horseshoe Lake is not too harmful to humans, because it limits the harmful levels are 1.75 million tonnes. And this will only happen in the event of the mountain erupted.
