An EUMETSAT handout shows the ash cloud (reddish colour) from the Grimsvotn volcano in Iceland. The photo was taken by the AVHRR Instrument on Metop-A polar-orbiting satellite on 23 May 2011 11.49 UTC. Airspace over Iceland was closed on 23 May 2011 after the North Atlantic country’s most-active volcano continued to spew ash. The plume above the Grimsvotn volcano was 23 May estimated to be between 8-10 kilometres, the Icelandic Meteorological Office said. The volcano began to erupt 21 May, and the plume was initially more than 20 kilometres high.
