• Resumen

  • Luca Caricchi of the University of Geneva in Switzerland and his colleagues simulated 1.2 million eruptions, varying factors such as the size, average flow of new lava and the pressure change required to cause an eruption. Their models suggest that supervolcano chambers fill slowly with hot magma which is less dense than the cooler crust around it. Like a beach ball held underwater, it eventually bursts through the top in a massive eruption.
