Kolka Glacier collapse, Russia, September 2002:

This image of Mt. Kazbek was taken from the Space Shuttle on October 17, 2002 (after the collapse of the Kolka glacier). It provides a comparative view with the previous image taken from the International Space Station on August 13, 2002 (before the glacier collapsed on September 20 - image ISS005-E-9691). The astronauts took the images at the request of the Russian URAGAN project, which is studying changes in the world’s glaciers in response to global climate change. Although scientists have predicted the possibility of large glacial collapses as the climate warms, no one predicted that tragedy would strike the mountain village of Karmadon, when the first image was taken.

This image shows the debris flow down the valley after the collapse. The red arrows point to the same location in both images. The debris flowed over the end of the Mail glacier (lower right arrow), and completely filled the valley below (upper-most red arrow). The left arrow points to a new lake that was formed because of disrupted drainage after the avalanche. Scientists studying the Kolka glacier after its collapse used aerial photography, ASTER imagery, Landsat Imagery, and Astronaut Photography from ISS in their analyses and in their filed work.
