Then, on the evening of August 21, 1986, it exhaled. Between 100,000 and 300,000 tons of carbon dioxide - odorless, colorless, heavier than air - erupted from Lake Nyos in a phenomenon scientists would later call a limnic eruption. The gas cloud rose at nearly 100 kilometers per hour, then sank, hugging the ground as it poured down the surrounding valleys. In the villages of Nyos, Kam, Cha, and Subum, 1,746 people died, most of them in their sleep. They never knew what was happening.

Carbon dioxide seeps upward from below, dissolving into the cold, pressurized water at the lake's bottom...

The cloud that erupted from Lake Nyos did not disperse upward and dissipate. It flowed downhill like an invisible flood, roughly 50 meters thick, traveling at 20 to 50 kilometers per hour through the valleys where people lived and farm...

Together, they remain the only two recorded limnic eruptions in history. After Nyos, scientists understood ...

Scientists surveyed other African crater lakes and turned their attention to Lake Kivu, straddling the border of the Democratic Republic of the Congo and Rwanda. Lake Kivu is 2,000 times larger than Nyos and was found in 2005 to be su...
