#Supervolcanoes are distinct #thermodynamic entities defined by the explosive ejection of over 1,000 cubic kilometers of bulk deposits (VEI 8) and the subsequent formation of massive #calderas through crustal collapse rather than edifice construction. There's no doom and gloom here, you might just as well relax a bit.

#Volcanic #Supereruption May Have Aided #Human #Exodus From Africa
#Researchers working in the #Horn of Africa have #uncovered evidence showing how #Middle #Stone Age humans #survived in the wake of the #eruption of #Toba, one of the largest #supervolcanoes in #history some 74,000 years ago. The behavioral flexibility of these Middle Stone Age people not only helped them live through the supereruption but may have facilitated the later dispersal of modern humans out of Africa and across the rest of the world.

“Our calculations also show that we are now currently emitting carbon dioxide 200 times faster than those supervolcanic eruptions that caused the most severe mass extinctions.”
