Supervolcanoes are considered one of the most destructive geological formations.
Scientists under the direction of archaeologist Marina Curtis (Curtis W. Marean) from the University of Arizona concluded that during the eruption of the Indonesian SUPERVOLCANO Toba some 74 thousand years ago in South Africa lived a group of people whom the disaster is almost not affected. The article was published in the journal Nature.
Researchers estimate the mass of ash and dust released into the atmosphere due to the super eruption, caused a reduction in the number of incoming to the surface solar light to 25-90 percent. However, some ecosystems were more resistant to disaster than others.
Scientists have found fragments of volcanic glass associated with You, in the sediments at two sites of the South African coast at nine thousand kilometers from the volcano. These fragments fell together with the ashes within two weeks after the eruption, when the air was thrown a huge amount of aerosols.
The researchers also analyzed the traces of human presence in those areas where we found volcanic glass. It turned out that the people of South Africa have not suffered from Toba and lived in the region, without the need for migration to more favorable locations. This is because the coast plays the role of a oasis can provide enough food and resources for survival for a long time.
Supervolcanoes are considered one of the most destructive geological formations that affect the climate of the planet. Toba, according to experts, could cause a mass extinction of species on Earth and cause a sharp global cooling.
