The current study, published in the journal Cell, also demonstrates human mobility, and hence connectivity, across Eurasia during the Early Bronze Age.

A few hundred kilometers north-west, three other islands still have their volcanic histories from a few million years ago mostly intact. No explosions there. So why the differences between the Santorini caldera and the Aegina, Methana and Poros lava domes? Researchers used volcanic “fingerprints’ and plate tectonics research to find out why.
