Russian Bezymianny Volcano From Space {Photo of the Day}

The Russian volcano Bezymianny erupted on the morning of April 14, this year. The images below were taken over a week later on the 22nd, and shows the extend of the eruption by the the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite.

The above natural colour image shows evidence of the size of the eruption. The dark volcanic deposits off to the right of the image are probably pyroclastic flows and lahars, and extend more than 7.3 kilometer (4.5 miles) into the southeast valleys. Volcanic ash is still covering the upper slopes of the volcano, especially to the south and west, and a plume of ash, steam, and sulfur dioxide rises above Bezimianny’s summit and is seen blowing to the west.

The above false colour image shows more features of the active volcano that could not be seen in a natural colour image. The red hot spot shown on the image could be where fresh lava is flowing from the lava dome, and to the southeast can be seen an active lava flow.

In a false colour image, bare rock and ash are grey, and snow and ice appear as cyan.

The Joint Air Force and Army Weather Information Network reported that on the morning of the eruption ash was reaching as high as 25,000 feet (7,600 meters) above the volcano.
