Researchers at the National Aeronautics and Space Administration NASA reported that life on Earth is threatened by supervolcanoes, whose eruption will lead to the death of all life. This is what we will discuss in this issue.
At the moment, there are 20 so-called super-volcanoes on Earth, the eruption of any of which can lead to the death of mankind. The main threat is considered the Yellowstone volcano, located in one of the national parks of the United States. Based on research, its last eruption occurred about 640 thousand years ago, as a result of which a huge depression of 150 kilometers formed in the earth. In this case, the repetition of events can happen in the next century.
Seismologists working in this area constantly record mini-earthquakes that do not threaten the lives of people, but they say that the volcano slowly comes to life. Under its crater there is a huge bubble of magma about 8 kilometers deep, and the temperature inside it exceeds 800 degrees Celsius. Scientists estimate that if this bubble burst and an eruption occurs, then nothing alive will remain within a radius of 100 kilometers, while the neighboring states will be covered with a meter layer of ash. But this is not the worst.
A suspension of dust and gas that would be emitted into the atmosphere would cover most of our planet. As a result, sunlight will completely cease to flow to the surface of the Earth, which will inevitably lead to a volcanic winter for many decades. As a result, most of the harvest will die, and animals, however, like people, are threatened with total extinction.
However, NASA is already developing plans to save humanity. Scientists want to pump water into a volcanic hole, which will pass through, cooling the crater. As a result, the resulting geothermal energy can be converted into electricity using turbines generating it.
In conclusion, we would like to say that supervolcanoes are far from the only danger to humanity. We told about other doomsday scenarios in a special issue, a link to which you will find at the end of this video.
