A buildup of carbon dioxide fuel isn’t unusual for crater lakes, with a lot of them sometimes releasing bubbles of it over time. Volcanic exercise happening under the Earth’s floor (and under the lake itself) will trigger gasses to seep up via the lakebed and into the water. One thing that typically is not a priority as deeper, colder water is ready to soak up substantial quantities of carbon dioxide, but when the focus will get too dense it may possibly create bubbles that float as much as and burst on the floor of the water.
This in itself is frequent, and the quantity of carbon dioxide often launched on this method will dissipate into the air shortly. Nevertheless, it is theorized that Lake Nyos had been amassing an uncharacteristically great amount of fuel resulting from a mixture of things like location, native local weather, general depth, and water stress. As soon as that buildup had been disturbed, all of it got here rocketing out.
Whether or not it was resulting from a rock slide, robust winds, or an sudden temperature change throwing off the fragile steadiness continues to be unknown. However regardless of the catalyst was, it induced the decrease layer of deep, carbon-infused water to begin to rise. Which then started to heat up, decreasing its potential to include the fuel. The ensuing perpetual cycle of rising waters and gasses creates the kind of explosion you would possibly see after opening a carbonated beverage after it has been shaken vigorously.
