#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.English https://www.miragenews.com/volcanic-supereruption-may-have-aided-human-1199293/

The Bandelier Tuff (New Mexico) ejected perhaps 800 cubic km of magma and rock in two events a little over 1 million years ago.
Trace elements in #quartz make it glow in an electron beam (cathode luminescence). The outer bright blue rims in CL record crystallization temperatures (from Ti concentrations) abruptly 100°C hotter than before: magma recharge triggering a #supereruption.
Jack Wilcock's M.Sc. work (John Stix's group).
