They come galloping out of the volcanic storm, hooves muffled in the ash, manes flying. 24 hours earlier he had lost the shaggy Icelandic horses in an ash cloud that turned day into night, blanketing the landscape in sticky gray mud.

The erupting volcano in Iceland sent new tremors on April 19, but the ash plume which has caused air traffic chaos across Europe has dropped to a height of about 2 km (1.2 mi), the Meteorological Office said.
