Mt. Etna, Sicily:This view of northeast Sicily shows two distinct atmospheric plumes being blown in a southeasterly direction during the summer 2001 eruption of Mt. Etna. The darker looking airborne plume is mainly an ash cloud that is being produced from an eruptive fissure along the southern flank of the volcano. The lighter colored plume is smoke that is coming from the cluster of vents located at the summit area of the volcano. The sizeable roughly circular base of the volcano is extensive, exceeding 60 kilometers (37 miles). The southwest view of the image shows the relationship of erupting Mt. Etna with the rolling fertile farmlands to the south and the mountains north of the volcano. The Peloritani Mountains of northeast Sicily present a rugged topographic landscape.
