the engineers here work 2a hours a day in 12 hour shifts, monitoring the conditions of the lake. kevu of yea rs of carbon dioxide from millions of years of decomposition and volcanic activity. these gases are kept under pressure at significant depths. the la ke pressure at significant depths. the lake is 480 metres deep, however, any disturbance to the lake from seismic activity or alaba flow could result in the gases leaking out. is one of only three known lakes in the world where the specific conditions for this catastrophic event could occur. they are known as the killer la kes. occur. they are known as the killer lakes. in 1986, a similar lake in cameroon suffered a carbon dioxide leak. the resulting gas cloud killed over 1700 people in nearby villages and all other living creatures in its path. in the gases —— if the gases lake kevu escaped it could be more deadly, it is 1700 times bigger than the one in cameroon and millions live around it. in lake kevu there is a lot more concentration which is far more than in the one in cameroon, so this is why it's very important to embark o
