These images from the Multi-angle Imaging SpectroRadiometer (MISR) capture the energetic eruption of Sicily's Mount Etna volcano on October 29, 2002. Viewing Etna's eruptive activities at MISR's multiple observation angles reveals the structure and relative heights of several plumes emanating from the volcano. The image panels are a natural-color view from MISR's vertical-viewing (nadir) camera (top), and a 3D stereo anaglyph (bottom). In the anaglyph, data from the 70-degree and 60-degree forward-looking cameras are displayed as red and green-blue, respectively. (For the 60-degree camera, 275-m red band data were used to spatially "sharpen" the green and blue 1.1-km resolution imagery). With the aid of red-blue glasses, the three-dimensional nature of the ash plume and the relative heights of plume and clouds can be discerned. Glasses should be worn with the red filter placed over your left eye. [0003-0701-0121-2639] by 0003
