'In the meantime our operations to and from northern Europe are operating normally,' an Emirates spokesperson said. said. Meanwhile, Iceland has lowered its warning code for possible volcanic disruption to the aviation industry to orange from red after further analysis of an apparent eruption under a glacier found there had been no eruption after all, a Reuters report said. The risk level had been raised to red, the highest level on the country's five-point alert system, on Saturday after authorities detected signs of a small eruption beneath a glacier near the Bardarbunga volcano in central Iceland.
