Ongoing eruptions of Russiaï¿½s Shiveluch and Klyuchevskaya Volcanoes continue to change the look of the landscape in images captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAï¿½s Terra satellite. This image from March 10, 2005, shows the two volcanoes rising up from the snowy terrain of the Kamchatka Peninsula in far northeastern Russia. Shiveluch has been producing many ash plumes throughout the first few months of 2005, and evidence of a recent eruption is scattered down the western flanks of the volcano and beyond. Meanwhile, a dark ring is encircling the slopes of the Klyuchevskaya Volcano, probably a mixture of ash, mudflows and melting snow and ice.
Eruptions at the Klyuchevskaya Volcano are becoming increasingly violent, prompting officials to raise the volcanic alert to its highest level, reserved for major explosive eruptions. (The volcano's name has many alternate spellings, including Klyuchevsky; Kluichevsky and Kluichevskaya; and Kluichevskoi.)
