Iceland removed a ban on air traffic around the nation’s largest volcanic system on Sunday after fears of an imminent eruption subsided. The Icelandic Met Office said there had not been a small, subglacial eruption on Saturday, as previously announced, and lowered the alert over the Bardarbunga volcano from red to orange. “Presently there are no signs of ongoing volcanic activity,” the IMO said on its website. “All restrictions on aviation have been cancelled,” Icelandic police said in a statement.
