London : 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.

Researchers from the University of Edinburgh in Britain found a staggering 91 previously unknown volcanoes, adding to the 47 others that had been discovered over the previous century of exploring the region.

These newly discovered volcanoes range in height from 100 to 3,850 m, with the highest almost as tall as Switzerland’s 3,970-m 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.According to geologists, this huge region is likely to dwarf east Africa’s volcanic ridge — currently rated as the densest concentration of volcanoes in the world.However, the activity of this range could have worrying consequences, glacier expert Robert Bingham was quoted as saying to the Guardian.

“If one of these volcanoes were to erupt it could further destabilise west Antarctica’s ice sheets,” Bingham warned.

“Anything that causes the melting of ice, which an eruption certainly would, is likely to speed up the flow of ice into the sea,” he said
