Melting #Antarctic ice sheets may be causing larger volcanic eruptions
During #deglaciation, melting of kilometers-thick #IceSheets reduces the mass weighing down the land, which leads to #uplift. This alters the pressure inside #magma chambers lying below the Earth's surface, causing #volcanic eruptions.

#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/

" #Iceland has 32 #volcanic systems that are considered active, the highest number in Europe. The country has had an #eruption every five years on average."
