About Erupting Lakes
So what is an erupting lake? It is basically when a bubble of methane (aka natural gas) or carbon dioxide gas gets jarred loose from the bottom of a lake. We have all seen a similar thing happen everyday when we pour a soft drink into a glass. It forms bubbles and after a while they simply float to the top.  
A lake eruption is just like that with some very important major differences. The gas that is the bubbles in a lake eruption is under the pressure a lake. In fact the pressure is so great that once it reaches the top of the lake and hits the atmosphere that it expands and mixes with the atmosphere almost instantly. What happens next depends on the composition of the gas.
If the composition of the gas is methane it could possibly explode after coming in contact with the smallest spark. If the composition of the gas is carbon dioxide it will instantly smother anything that breaths or needs oxygen.  

What Is Carbon Dioxide
Simply put, its oxygen that has been used. Although it is commonly thought that we exhale carbon dioxide, it only makes up about .5% of what we exhale.  What can make it deadly is that it is heavier than most air as such a mixture of as little as 10% in the air can prevent the intake of oxygen.  

What is Methane
This is simply the scientific word for natural gas that some use to heat their homes. It is highly flammable and burns very hot.

Lake Eruptions In Action
In 1984 Lake Monoun erupted and suffocated over 36 people. About two years later on August 22, 1986 in the middle of the night, over 1700 villagers, 3000 cattle and many other animals were killed when Lake Nyos erupted.

Differences Between Lake and Oceanic Eruptions
Technically speaking the same things happen except one is in a lake and one is in the ocean. As such the bubble in an oceanic eruption is under far greater pressure.  


Oceanic Eruption Theories
It is believed that at one time the oceans erupted a giant bubble of methane gas which subsequently ignited killing a good portion of life on the planet.  Here is part of an article on another website where Ryskin explains this theory quite well. I have added the part in this article that was left out in white (prepare for a small shock) but if you use your imagination just imagine what would happen if say the Atlantic ocean blew up (love the polite way he put it) :



Ryskin asked what would happen to that gas in a stagnant ocean basin. His answer, in the September 2003 Geology, is an oceanic eruption driven by explosive methane. The scenario is horrifying in several ways.

Enough methane dissolves in deep, cold water (about 0.4 percent by molar volume) if that water were to rise, the gas would come out of solution and create a mist whose volume is seven times greater than pure water. The resulting eruption would quickly spread and release the whole ocean basin's worth of natural gas in great clouds. These would inevitably ignite [with the force of several hundred hydrogen bombs]. The amounts of gas would be enormous, and the worldwide fires and explosions would be catastrophic. Even the formation of fullerene compounds, now considered a sure sign of asteroid impacts, is plausible. Land organisms would suffer mass extinction...

Oceanic Eruption Fear in Gulf

This is an interesting video that I found. There is a lot on this subject so I'm not going to add much more to this post other than at the time that the video below was made there was a huge scare that the methane gas being released would explode and toast the southeastern part of the US.  This scare was big enough that US military moved its fleets away from the area.

Here is a video on our Youtube channel which demonstrates a lake eruption.

i would laugh if that happened to more humans.

In this case close could be anywhere from 1-300 miles (if not more) The thing is the gas as it comes up is highly compressed and so when it hits the surface and decompresses it would spread into the atmosphere almost instantly.

If it were carbon dioxide, it would smother everyone within minutes. If the gas released was methane it could ignite at the first spark. Remember, methane is natural gas and is highly flammable.

For more info do a search on Lake Nyos for the year of 1986.
