‘Cauldrons’ Found At Iceland’s Largest Volcano Could Spell Big Trouble
Ice over Iceland’s rumbling Bardarbunga volcano has melted to reveal a row of one-kilometer wide “cauldrons,” possibly due to a sub-glacial eruption, the country’s meteorological office said late on Wednesday. Rumblings at Iceland’s largest volcano system for about a week have raised worries of an eruption that could spell trouble for air travel. In 2010, an ash cloud from the Eyjafjallajokull volcano closed much of Europe’s airspace for six days.
