In this photo taken on Saturday, May 21, 2011, smoke plumes from the Grimsvotn volcano, which lies under the Vatnajokull glacier, about 120 miles, (200 kilometers) east of the capital, Rejkjavik, which began erupting Saturday for the first time since 2004. Iceland closed its main international airport and canceled domestic flights Sunday as a powerful volcanic eruption sent a plume of ash, smoke and steam 12 miles (20 kilometers) into the air.
