The Terrifying Phenomenon of Limnic Eruptions: Unpredictable Natural Disasters in Lakes
TLDR Limnic eruptions, rare and terrifying natural disasters, can occur in lakes without warning, causing the water to rise and flood the surrounding area. These eruptions, caused by the release of CO2 gas, have resulted in deaths and destruction in the past, and there are concerns about potential future eruptions in certain lakes.
Timestamped Summary
00:00
A limnic eruption is a rare and terrifying natural disaster that occurs in lakes, causing the water to rise and flood the surrounding area without any apparent cause or warning.
02:23
In 1984, a mysterious gas cloud arose over Lake Monoun in Cameroon, killing 37 people and leaving behind crushed plants and damaged skin, leading to speculation of terrorism, but two years later a similar event occurred at Lake Nios, also in Cameroon.
04:05
In 1986, a limnic eruption occurred at Lake Nios in Cameroon, resulting in the deaths of 1,746 people and 3,500 cattle, with witnesses describing the scene as if it had been hit by a neutron bomb.
05:48
Meromictic lakes, which have layers of water that do not mix, can accumulate a large amount of dissolved CO2 at the bottom, and when this water is disturbed, it can result in a massive release of CO2 gas, similar to opening a can of soda.
07:32
CO2 gas released from limnic eruptions can sit in the air until it dissipates or flow downhill, depriving engines of oxygen and causing asphyxiation, and Lake Kivu on the border of the Democratic Republic of Congo and Rwanda is a candidate for a limnic eruption that would be far worse than any previous eruptions.
09:13
Lake Kivu is at risk of a limnic eruption due to increasing levels of CO2 and methane, and there is a concern that methane could ignite if released to the surface, while Crater Lake in Oregon is not at risk due to its colder temperature and constant convection preventing CO2 buildup.
10:59
Lymnic eruptions are rare and require specific conditions and triggers, but with knowledge and identification of potential lakes, disasters can be prevented.
