Satellites look into a volcano's hell
This view of Tolbachik Volcano on Russia's Kamchatka Peninsula was captured in infrared and noticeable light on Dec. 1 by the Advanced Land Imager on NASA's Earth Observing 1 satellite. The infrared readings in red highlight hot lava flows from the volcano. By Alan Boyle
Smoke and lava issue forth from Russia's Tolbachik Volcano in a pair of images from NASA's Earth Observing 1 satellite. What a difference in the perspectives! The visible-light view from EO-1's Advanced Land Imager, captured on Dec. 1, reveals billows of ash and vapor, with a stream of dark lava cutting across the landscape. On the other hand, the infrared-plus-visible view reveals a nightmarish red river, running through a bilious green landscape. This version of the scene gets its eerie look from the untrue colors utilized to represent different wavelengths in the infrared part of the spectrum.
