Supervolcanos proved to be incapable of destroying humanity
Scientists led by archaeologist Curtis W. Marean from the University of Arizona came to the conclusion that during the eruption of the Indonesian super volcano Toba about 74 thousand years ago in South Africa there were groups of people who were not affected by the disaster. The article was published in the Nature journal.
According to researchers, the mass of ash and dust, trapped in the atmosphere due to super-eruption, caused a decrease in the amount of sunlight entering the surface of the Earth by 25-90 percent. However, some ecosystems were more resistant to disasters than others.
Scientists have found fragments of volcanic glass associated with Toba, in sediments on two sections of the South African coast, nine thousand kilometers from the super volcano. These fragments fell out with ashes within two weeks after the eruption, when a huge amount of aerosols were thrown into the air.
Researchers also analyzed traces of human presence in those areas where volcanic glass was found. It turned out that the people of South Africa did not suffer from Toba and lived permanently in the region without experiencing the need for migration to more favorable locations. This is because the coast, playing the role of a kind of oasis, could provide enough food and resources to survive for a long time.
Supervolcanos are considered to be one of the most destructive geological formations that influence the climate of the planet. Toba, according to experts, could cause a massive extinction of species on Earth and cause a sharp global cooling.
