DEM of Kamchatka Peninsula, Russia
This Digital Elevation Model (DEM) from the TanDEM-X mission shows an area on the Kamchatka Peninsula in the northeast of Russia.
Wide expanses of the Pacific plate press against the Eurasian plate, causing unique volcanic activity with an very high density of volcanoes. Of the over 160 volcanoes, 29 are currently active and six of them erupt on average each year. Kamchatka is known as the 'Land of Ice and Fire' due to its combination of snow and ice and its high level of volcanic activity. Its highest peak is the 4835-metre Kliuchevskoi. The simultaneous eruption of four volcanoes (Shiveluch, Bezymianny, Tolbachik and Kizimen) in January 2013 catapulted the region into the headlines. UNESCO declared the volcanic region of Kamchatka a Natural World Heritage Site in 1996.
Together with TerraSAR-X, TanDEM-X has already travelled 800 million kilometres at an altitude of 514 kilometres, scanning Earth's entire land surface more than twice. The satellites move around one another in a helical pattern, at times imaging Earth while separated by only 120 metres.
DLR are using the data acquired by these satellites to form elevation models of the Earth's surface, which when complete will form a new highly accurate topography of the world.
