Icelandís Grimsvotn Volcano
On May 21, 2011, Icelandís Grimsvotn Volcano erupted, sending an ash plume 12 miles (20 kilometers) high and closing Keflavik Airport, Icelandís largest. Ash fell on much of Iceland, with some areas pitch black at midday on the 22nd. This eruption is not expected to disrupt air travel as much as taht of Eyjafjallajokull in 2010 because the Grimsvotn ash particles are larger and settling out of the atmosphere more quickly.
This natural-color satellite image, acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite, shows the towering ash plume at 1:00 p.m. local time. Beneath the ash plume, clouds cover much of the scene. Lingering snow is visible beneath the clouds to the northeast (upper left). Brown ash covers a portion of the Vatnajokull Glacier near the Atlantic coast (lower right).
Grimsvotn is Icelandís most active volcano, but it hasnít erupted so forcefully since 1902. The lava is basaltic, which typically erupts in non-explosive, Hawaiian-style eruptions. Grimsvotn is located beneath a glacier, however, and the interaction of melting ice with the lava can create an explosive eruption, at least in the initial stages.

Looks kind of like an aerial view of Al Gore's mansion."Our president delivered his State of the Union message to Congress. That is one of the things his contract calls for -- to tell congress the condition of the country. This message, as I say, is to Congress. The rest of the people know the condition of the country, for they live in it, but Congress has no idea what is going on in America, so the president has to tell 'em." ~ Will Rogers

heat their homes and pipe steam to generate electric power .There must be some enormous magma chambers under the entire country .They're on the edge of two large tektonic plates .
Gore would just blame it on global warming and demand a few billion form America for causing it !
