<P> The 2010 eruptions of Eyjafjallajökull were volcanic events at Eyjafjallajökull in Iceland which , although relatively small for volcanic eruptions , caused enormous disruption to air travel across western and northern Europe over an initial period of six days in April 2010 . Additional localised disruption continued into May 2010 . The eruption was declared officially over in October 2010 , when snow on the glacier did not melt . From 14 -- 20 April , ash from the volcanic eruption covered large areas of Northern Europe . About 20 countries closed their airspace to commercial jet traffic and it affected approximately 10 million travellers . </P>
