This astronaut photograph of snow-covered volcanoes on Russia’s Kamchatka Peninsula illustrates one of the unique attributes of the International Space Station—the ability to view landscapes at an angle, rather than the straight-down view typical of many satellite-based sensors. This oblique view, together with shadows cast by the volcanoes and mountains, provides perspective about the topography of the region.
Kronotsky and Kizimen stratovolcanoes are distinguished by their symmetrical cones. Kizimen last erupted in 1928, while Kronotsky—one of the largest on the peninsula—last erupted in 1923.
Schmidt Volcano, to the north of Kronotsky, has the morphology of a shield volcanoand is not known to have erupted since humans have been keeping records.
To the south (left) is Krasheninnikov, comprised of overlapping stratovolcanoes that formed within an earlier caldera. Krasheninnikov may have last erupted in 1550. Two summit craters are clearly visible.
Lake Kronotsky is Kamchatka’s largest lake. It formed when lava flows from Kronotsky Volcano dammed the Listvenichnaya River.
The Kamchatka Peninsula lies along the so-called Pacific “Ring of Fire.” The ring is characterized by active volcanoes and frequent earthquakes associated with the many active and transformboundary zones around the Pacific tectonic plate. There are 114 volcanoes on the Kamchatka Peninsula that have erupted during the Holocene Epoch (approximately 12,000 years ago to the present).
Astronaut photograph ISS025-E-17440 was acquired on November 19, 2010, with a Nikon D3S digital camera using an 800 mm lens, and is provided by the ISS Crew Earth Observations experiment and Image Science & Analysis Laboratory, Johnson Space Center. The image was taken by the Expedition 25 crew. The image in this article has been cropped and enhanced to improve contrast. Lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Caption by William L. Stefanov, NASA-JSC.
