Volcano Bardarbunga- ICELAND, the expert: The magma has risen from the mantle. Images from space meteoweb.eu/2014/09/vulcano-bardarbunga-lesperto-magma-r... https://translate.google/translate?sl=it&tl=en&js=y&... Thursday, September 4, 2014 The most significant image comes from the Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite, which acquired data in false color using a combination of infrared light and visible (MODIS bands 7-2-1). September 1 is touched the Advanced Land Imager (ALI) on NASAs Earth Observing-1, whose image shows a crack of 1 km and the lava flowing into its various channels. The flow front has moved mostly to the north-east in recent days and the intense earthquake swarm near the volcano began on August 16 2014 Since then, large amounts of magma formed a layer of rock just cooled down, called dam, which stretches for about 45 kilometers north of Bárdarbunga The huge volume of magma involved suggests that it is climbed directly from the Earths mantle, says Evgenia Ilyinskaya, a volcanologist at the British Geological Survey in Edinburgh. The source, therefore, would be located hundreds of miles below the surface of the crust rather than in a magma chamber surface common to many volcanoes.
