What is a limnic eruption?
An easy way to answer that question would be you have a soda can filled with carbon dioxide, you then shake the can, open it and the carbon dioxide spills out everywhere suffocating everything in it’s at was the short way of saying it. The long way is that a limnic eruption is an extremely rare natural disaster, where a high level of co2 erupts from deep in a lake, forming a giant gas cloud of co2 capable of suffocating wildlife and humans. Where can it occur? A limnic eruption can occur anywhere but it has to have these requirements; near a volcanic field, a high build up of dead vegetation near or even in the lake and/or an upper or lower layer with different co2 saturations an example of a limnic eruption is at lake Nyos, where a giant gas cloud of co2 with a diameter of 80 cubic metres, killing 1700 people.

What devastating effects does it have on the earth’s surface? A limnic eruptions’ causes are high vegetation levels and magma underneath the lake; creating the co2. The disaster forms overtime as the co2 needs time to travel through the soil and into the lake. Something else can also trigger it as small as some wind, rain or even a landslide can set off this rare disaster. The effects that it has on the earth’s surface are high co2 levels in the air making it hard to breath, loss of vegetation (suffocated) humans and livestock as well as the lake being filled with deadly chemicals. So limnic eruptions are dangerous, but on the other hand, it can help the land like a bushfire, getting rid of the vegetation as new seeds create new vegetation and wildlife.

The destruction of a limnic eruption. The types and strengths of this disaster are like no other disaster this disasters’ strengths are based on its cubic metres. The only other types of eruptions relating to it are volcanic and solar. There are no actual strengths of this disaster, as previous ones have only had a high amount of co2 in the air concluding to be a tsunami-like wave of co2. The destruction. Asphyxia. Asphyxia is sort of like a heart burn. When the co2 wave rolls over you, your skin turns yellow and you get blisters on your body. Aside from that there will be a definite loss of vegetation, whether it’s overtime or even if it’s slowly decaying, there will be a definite loss of vegetation. A loss of livestock and humans will also occur. Alternatively, if the towns near the the previous 2 limnic eruptions had known what it was, they would have been able to evacuate and survive.

How to survive a limnic eruption. The warning signs of a limnic eruption are quite noticeable. They include bubbles atop the lake and high co2 levels. 300 survivors of the past eruption reported a smell of rotten eggs, they also said they felt warm before they passed out. Another sign will be that no animals will be drinking from the lake or near the lake. The safety precautions that people can follow are, oxygen masks, to help breathe and to also protect yourself from co2 poisoning, evacuation (trying not to breathe, nor panic, save your breath to run and escape the poisonous gases. Finally, don’t run to get to safety as you will run out of breath and have a 70% chance of getting co2 poisoning, as you will be puffing for added air. Try and escape by a vehicle, it will be much quicker, but don’t turn on the aircon! Going to higher ground will help your chances also as you can get out of the deadly tsunami. To summarise, check with your local government to see if there is a chance that there could potentially be a limnic eruption near you.

A limnic eruption has magma underneath the lake and can be triggered by anything larger than a gust of wind. The effects of the eruption can be devastating on livestoc, people, vegetation and more. A limnic eruptions strengths are based on its cubic metres and if it’s near you, you could get asphyxia. If you’re fishing camping or hiking near a lake and feel warm or smell rotten eggs, get to high ground via a vehicle. Following on from this disaster, scientists have installed co2 pumps into all lakes that have the symptoms which will pump out all of the co2 in the lake- so that hopefully we will not have another disaster like this again.
