Volcanoes erupt completely differently to how we thought

NEWS… BUT NOT AS YOU KNOW IT

Scientists have always believed that it was water along with shallow magma stored in the Earth’s crust that pushed volcanoes to erupt.

Now, new tools have proved this theory wrong, with researchers concluding that it is carbon dioxide that triggers explosive eruptions.

A new model suggests that basaltic volcanoes are fed by a deep magma within the mantle, stored about 20 to 30 kilometres below Earth’s surface.

‘We used to think all the action happened in the crust,’ said senior author Esteban Gazel.
