According to a report by the BBC, even NASA sees it as one of the greatest natural threats to humanity: supervolcanoes.
How does a ‘supervolcano’ eruption work?
Below Yellowstone National Park, there’s a huge magma reservoir that’s responsible for all the geysers and hot basins, bubbling away — and it’s precisely this reservoir that has the potential to destroy humanity.
Roughly every 100,000 years, there’s a supervolcano explosion somewhere in the world, the consequences of which can be fatal.
If the volcano below Yellowstone National Park were to erupt, it would result in worldwide hunger and a volcanic winter (the cooling of the lower atmosphere).
