Walking on the glacier under the ash plume

In April-May 2010 the Eyjafjallajökull volcano, in Iceland, produced one of the most hazardous eruptions over the last years emitting huge amounts of ash into the atmosphere. Most of this activity affected the air traffic, causing the disruption of hundreds of commercial aircrafts of a high number of airline companies. Since mid-May, the explosive activity strongly declined, thus permitting us to approach the summit of the volcano in order to collect tephra samples and record video-footages of the last days of the eruption.
