The largest volcanic region on Earth — with nearly 100 volcanoes — has been discovered two km below the surface of the vast ice sheet in west Antarctica.
The height of these newly discovered volcanoes range from 100 to 3,850 metres, with the highest almost as tall as Switzerland’s 3,970-metre Eiger Mountain.
These active peaks are concentrated in a region known as the west Antarctic rift system — which stretches 3,500 km from Antarctica’s Ross Ice Shelf to the Antarctic Peninsula.
Geologists say this huge region is likely to dwarf east Africa’s volcanic ridge — currently rated as the densest concentration of volcanoes in the world
