Summary

[edit]
Description
English: Nearly three months after Tolbachik began erupting, lava continues to flow from the Kamchatkan volcano. Over time, the lava flows change location and shift across the landscape. In this image, infrared data is superimposed on a natural-color image to highlight active flows. The image was collected by the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite on February 14, 2013.
The Advanced Land Imager detected the infrared light emitted from recent and ongoing lava flows. Near infrared light detected by ALI is colored yellow, and shows the erupting vent and an active lava flow, open to the air. Areas glowing in shortwave infrared light, including the fringes of the active flow, are tinted red. These surfaces are hotter than the frigid winter air of Kamchatka, but cooler than the channelized flowing lava. To the east, scattered red pixels reveal residual heat on a flow formed in early February.
