Sheep farmers try to round up a flock as they walk through a cloud of ash pouring out of the erupting Grimsvoetn volcano in Mulakot on May 22, 2011. Ash deposits were sprinkled over the capital Reykjavik, some 400 kilometres (250 miles) to the west of the volcano, which has spewed an ash cloud about 20 kilometres into the sky. Less than 24 hours after the eruption began late Saturday, experts and authorities in Iceland said the volcanic activity had begun to decline.
