Kizimen Volcano, which erupted for the first time in 81 years in December 2010, continues to emit gas and ash. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured these natural-color (top) and false-color (bottom) views of the eruption on November 1, 2012. Though the plume is difficult to detect in true color, it shows up clearly in false color because of the different combination of bands used to create the two images. In the false-color image, snow and ice appears bright red and vegetation looks green.

Clouds obscured Kizimen Volcano’s plume in this true-color satellite image, but in false-color the plume shows up clearly.
