	Lake Nyos Tragedy
		Lake Nyos is one of only three lakes in the world known to be saturated with carbon dioxide -- the others are Lake Monoun, also in Cameroon about 100 km away, and Lake Kivu in Rwanda.
		Although a sudden outgassing of CO had occurred at Lake Monoun in 1984, killing 37 local residents, a similar threat from Lake Nyos was not anticipated.
		Lake Kivu in Rwanda, 2000 times larger than Lake Nyos, was found also to be supersaturated, and geologists found evidence for outgassing events around the lake about every thousand years.

	Lake Nyos tragedy
		The Lake Nyos tragedy was a disaster that occurred on August 21, 1986, when a cloud of gas suddenly boiled at Lake Nyos[?], Cameroon, killing nearly 2000 people within a radius of 20 km.
		Lake Nyos is a deep lake that is thermally stratified: layers of warm, less dense water near the surface float on the colder, denser water layers near the lake's bottom.
		On August 21, water which was saturated with CO reached the surface, possibly due to wind or cooling of the lake's surface, and released enormous amounts of the gas which suffocated life throughout the region.

	Definition of Lake Nyos Tragedy
		The Lake Nyos tragedy was a disaster that occurred on August 21, 1986, when a cloud of carbon dioxide gas suddenly boiled at Lake Nyos, Cameroon, killing over 1700 people within a radius of 20 km.
		Lake Nyos is a deep volcanic crater lake that is thermally stratified, layers of warm, less dense water near the surface float on the colder, denser water layers near the lake's bottom.
		International efforts have since installed a pipe running from the surface anchored to a raft that allows the deeper areas of the lake to release their CO to the surface in controlled small amounts.

		Lake Nyos is one of only three lakes in the world known to be saturated with carbon dioxide -- the others are Lake Monoun, also in Cameroon about 100 km away, and Lake Kivu in Rwanda.
		The normally blue waters of the lake turned a deep red after the outgassing, due to iron-rich water from the deep rising to the surface and being oxidised by the air.

	Ramp of Terror
		Lake Nyos is a water-filled throat of an old volcano and it is deep and funnel-shaped.
		At Lake Nyos, once these bubbles started to form they wanted to rise to the top, this brought up more carbon dioxide-rich water which then also started to develop bubbles, and pretty soon there was a big rush of carbon dioxide bubbles to the surface.
		The problem is that there is this lake at an elevation higher than the main towns nearby, and if for any reason the walls of the lake were breached there would be a flood of water that could be just as dangerous as a flood of carbon dioxide.

		Because CO is denser than air, the gas flowed off the mountainous flank in which Lake Nyos rests and down two adjoining valleys in a layer tens of metres deep, displacing the air and suffocating all the people and animals before it could dissipate.

		Lake Nyos is a deep volcanic crater lake that is thermally stratified, layers of warm, less dense water near the surface float on the colder, denser water layers near the lake's bottom.
		On 21 August, the water became over-saturated with CO, resulting in gas coming out of solution bubbling up to the surface; this caused the water to turn over, bringing more of the saturated water to surface levels where it was no longer under pressure, releasing further gas.
		International efforts have since installed a pipe running from the surface anchored to a raft that allows the deeper areas of the lake to release their CO to the surface in controlled small amounts.

		Nyos was abandoned, but what no one knew was that new evidence was to be uncovered, evidence which would lead everyone on a journey into the unknown.
		Their first glimpse of the lake was puzzling and for George Kling who had been to the site just a year before it was something of a shock.
		The mystery of Lake Nyos was finally over, but now the scientists had worked out what had unleashed the monster from the depths of the lake they had to make sure it could never happen again.

	Gas threat grows from Cameroon's lethal lakes \| Science \| Guardian Unlimited
		Perched among the highlands of western Cameroon, bordered by green mountains and cliff faces, Lake Nyos is a scene of breathtaking beauty.
		Researchers called in after the 1986 tragedy discovered that the lake, which sits atop a volcano, contained record levels of carbon dioxide.
		The danger around Lake Nyos has increased in recent years as families evacuated for a generation since the 1986 eruption have started to move back, encouraged by the fertile farmland.

		Lake Nyos is located in western Cameroon, adjacent to Nigeria, in the elbow region of west Africa.
		It had been known for years that the water in Lake Nyos was extremely enriched in dissolved CO The lake overlies a volcanic source, which appears to release CO2 and other gases.
		Investigators from the U.S. concluded that this event was from the CO -rich bottom waters being overturned by a landslide, an earthquake, or abnormally heavy rains.

		The dam - a plug of volcanic waste on the north side of the lake - is close to collapse according to Nisa Nurmohamed, one of two UN experts who have investigated the state of the dam.
		This release of water would spark a second tragedy, releasing massive heavy clouds of poisonous carbon dioxide gases from the bowels of the lake into the atmosphere that would creep along the valley floor for many kilometres.
		But ultimately the goal is to make the lake safe so that the thousands of farming families that had to leave the lush valleys that abut Nyos, can return to their homeland.

	BBC ON THIS DAY \| 21 \| 1986: Hundreds gassed in Cameroon lake disaster
		It was finally concluded that the lake's lower levels had become saturated by carbon dioxide gas (CO2) due to gaseous springs which bubbled up from the extinct volcano beneath.
		Pipes have now been put in place in Lake Nyos and nearby Lake Monoun to siphon water from the lower layers up to the surface and allow the CO2 at the bottom of the lake to slowly bubble out, preventing a repeat of 1986 tragedy.
		It revealed that Lake Kivu, in Rwanda, is becoming saturated with carbon dioxide just as Lake Nyos was, and is seriously at risk of lake overturn.

		The tragedy of Lake Nyos, also in Cameroon, made headlines around the world when almost 1,800 people sleeping in houses around the lake suffocated in their sleep.
		Eventually the scientists came to realise that carbon dioxide springs underground were pumping carbon dioxide into the lake and that the whole tragedy would be repeated if nothing was done.
		Lake Kivu is one of the largest and deepest lakes in Africa and two million people live around its shore.

		However, on August 21, 1986, an event occurred at Lake Nyos which triggered the sudden release of about 1.6 million tonnes of CO The gas rushed down two nearby valleys, displacing all the air and suffocating up to 1800 people within 20 km of the lake, mostly rural villagers, as well as 3500 livestock.
