Russia’s northernmost territory, Franz Josef Land, is an archipelago of 191 islands in the northeastern Barents Sea. On August 17, 2011, clear skies allowed the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite this unobstructed view. Clouds fringe this natural-color scene, like curtains held back from a window. Around the islands, sea ice forms serpentine shapes of light gray and dull white. The glaciers that cap many of the islands are bright white. In ice-free areas, land cover is pale brown, typical of tundra. (via NASA Earth Observatory)

Earth from Space: Volcanic land (by europeanspaceagency) This Envisat image shows the eastern coast of the Kamchatka Peninsula, in Russia’s far east between the Pacific Ocean and Sea of Okhotsk. The central element shows an isolated volcanic group that includes the highest active volcano in Eurasia: Klyuchevskaya Sopka. This image is a compilation of three passes by Envisat’s radar on 1 June, 6 July and 10 August 2010. Each is assigned a colour (red, green and blue) and combined to produce this representation. New colours reveal changes in the surface between Envisat’s passes. Credit: ESA.

Omulyakhskaya and Khromskaya Bays lie along the northern Siberian coast, southeast of the Lyakhov Islands. The northerly location almost guarantees ice in the adjacent East Siberian Sea, and permafrost blankets the land around the bays. The Thematic Mapper on the Landsat 5 satellite captured this natural-color image on June 15, 2009, when ice lingered on the sea surface and on some inland water bodies. The land around the bays is dotted with thermokarst lakes, which result from water released by thawing permafrost. (…) Because thawing permafrost and thermokarst lakes release carbon and methane—both greenhouse gases—scientists monitor these landscapes closely because of their implications for future climate.

STS068-218-007 (30 September-11 October 1994) —- (Kliuchevskoi Volcano) The crewmembers used a 70mm camera to photograph this northeasterly looking view of the plume from the Kamchatka peninsula’s newly erupted volcano. The eruption was photographed from 115 nautical miles above Earth. Six NASA astronauts spent a week and a half aboard the Space Shuttle Endeavour in support of the Space Radar Laboratory 2 (SRL-2) mission.

This astronaut photograph highlights the summit crater and snow-covered slopes of the Avachinsky stratovolcano as it pokes above a surrounding cloud deck. The 2,741 meter (8,993 foot) high Avachinsky volcano has an extensive historical and geological record of eruptions. The latest activity occurred in 2008. (…) To the southeast (image right), the large breached crater of Kozelsky Volcano is also visible above the clouds. Kozelsky is a parasitic cone, formed by the eruption of material from vents along the flank of Avachinsky. (via NASA Earth Observatory)

Bezymianny Volcano erupted vigorously on the morning of April 14, 2011. The natural-color satellite image shows evidence of the large size of the eruption. Dark volcanic deposits (likely from a combination of pyroclastic flows and lahars) extend more than 7.3 kilometers (4.5 miles) into valleys southeast of the volcano. (…) A false-color image reveals more features on the active volcano. At the summit, a red “hot spot” may indicate where fresh lava is being extruded from the lave dome. To the southeast an active lava flow appears as a similar hot spot. These images were acquired near noon on April 22, 2011, by the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite. (via Bezymianny Volcano : Natural Hazards)
