Eyjafjallajokull eruption. Satellite image of the ash cloud (grey, centre) from the April 2010 Eyjafjallajokull eruption being blown towards Europe. The volcano erupted below the Eyjafjallajokull glacier in Iceland (outlined beneath the clouds at upper left) on 14 April, sending ash high into the atmosphere. The ash was then blown eastwards by the wind over the following day, leading to the airspace over the UK and other northern European countries being shut down due to the hazard the ash posed to aircraft engines. The northern tip of the UK is at lower right. This image was obtained at 11:35 UTC on 15 April 2010, by NASA's Terra satellite.
