This image, acquired today by ESA's Envisat satellite, shows the vast cloud of Eyjafjallajoekull volcanic ash sweeping across the UK from the eruption in Iceland, more than 1000 km away.
Carried by winds high up in the atmosphere, the cloud of ash from the eruption of the Eyjafjallajökull-Fimmvörduháls glacier in southwest Iceland has led to the closure of airports throughout the UK and Scandinavia, with further disruption in northern Europe expected later today. The ash, which can be seen as the large grey streak in the image, is drifting from west to east at a height of about 11 km above the surface Earth. It poses a serious danger to aircraft engines; hence the airspace shut down.
The Eyjafjallajokull volcano erupted, for the first time since 1821, on 20 March and started erupting for a second time on Wednesday. The volcano, under the glacier ice, has caused ice melt and subsequent flooding and damage locally.

This image was acquired on 15 April 2010, at 13.25 (CEST) by Envisat's Medium Resolution Imaging Spectrometer (MERIS) while working in Full Resolution Mode to provide a spatial resolution of 300 meters.
This animation shows the movement of the ash plume from the eruption of the Eyjafjallajoekull glacier in Iceland.
The information has been derived from SEVIRI instrument on board the Meteosat weather satellite in combination with a particle dispersion model. This model has been developed at the Norwegian Institute for Air Research in the Department of Atmospheric and Climate Research.
This service was developed within the ESA Data User Element 'Support to Aviation for Volcanic Ash Avoidance' with the aim of generating accurate and timely satellite-based information to Volcanic Ash Advisory Centres (VAACs) to assist the aviation community.
