Mount Etna, one of the world’s most active volcanoes, erupted in late October 2005. In mid-November, it was still emitting a sporadic plume of ash.
The Moderate Resolution Imaging Spectroradiometer (MODIS) flying onboard the Terra satellite captured this image of Etna on November 12, 2005. In this image, a faint plume of ash wisps away from the volcano’s summit toward the northwest. The satellite also captured the ash plume’s shadow, appearing just north of the plume itself. Running diagonally down the left side of the image is a seam, where two different satellite images were stitched together to make this picture.
