#6 – Lake Nyos
This majestically beautiful but extremely dangerous lake can be found in Northwestern Cameroon. What is this lake dangerous for? Well, given the fact that Lake Nyos on an area of extremely high volcanic activity where dangerous CO2 leaks from the ground, you can assume that this lake is extremely dangerous.
During something called “limnic eruption” which occurs in the volcano on whose top Lake Nyos located is, the CO2 bursts out from the lake’s bottom and forms an enormous, deadly cloud.
