On the morning of April 14, 2011 Russia’s Benzmianny Volcano erupted. The Joint Air Force & Army Weather Information Network reported ash to be as high as 25,000 feet into the atmosphere at the time of the eruption. What makes this eruption even more exciting is the fact that a satellite, the Earth Observing-1 (EO-1) satellite, just happened to be in range of the eruption. The satellite was equipped with the Advanced Land Imager, and took some amazing aerial photos of the eruption.
In the normal colored pictures, dark volcanic deposits (a mix of pyroclastic flows and lahars) stretch as far as 4.5 miles away from the volcano. The ash and snow of the surrounding area can be seen.
In the false-colored images, more activity of the volcano is revealed. A hot spot where the lave is flowing can be observed, as well as active hot lava flows. Rock appears as grey, and everything else appears as cyan.
