This Envisat MERIS image acquired on 25 November 2006 captures smoke spewing from Europe’s largest active volcano, Mt. Etna. The 3 350 metre-high volcano resumed eruptions in early September this year and entered its highly active phase on 5 November, according to the National Institute of Geophysics and Volcanic Studies.
