April 17, 2013 - Kamchatka Peninsula, eastern Russia
On April 4, 2013 NASA’s Terra satellite passed over Russia’s Far East, allowing the Moderate Resolution Imaging Spectroradiometer flying aboard to capture this stunning image of a wind-swept spring day on Kamchatka Peninsula.
Approximately 750 miles long and 300 miles wide, the remote, arrow-shaped peninsula is separated from the Russian mainland by the Sea of Okhotsk, and the Bering Sea lies to the east. On this day, heavy chunks of sea ice filled the northern Sea of Okhotsk, while filigrees of thinner ice formed fringes off the more southerly coasts of the peninsula. A bank of marine clouds lies over the Bering Sea, while a higher, thinner stream of clouds can be seen near the eastern edge of the image.
The Kamchatka Peninsula has the highest concentration of active volcanoes on Earth. Most of them, with names like Shiveluch, Bezymianny, Tolbachik, Kizimen and Klyuchevskaya, are located east of the Central Kamchatka Depression, towards the east and southeast coast. Another volcanic zone lies to the west of the Kamchatka River in the central and western sections.
In this image, the most easily recognized volcano is the massive Klyuchevskaya (Kliuchevskoi) Volcano which can be seen near the center of the image as a bright white mountain surrounded by a light gray depression. The summit rises to 15,000 feet, making it the largest active volcano in Eurasia.
