The forbidding slopes of Klyuchevskaya are covered in snow and barren rock. And at its peak, a volcanic eruption continues to spew ash and rock into the atmosphere.
According to NASA:
Klyuchevskaya Volcano on the Russian Federation's Kamchatka Peninsula continued to release a plume on June 12, 2010. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite captured this false-color image the same day.
This image uses a combination of visible and near-infrared light. Vegetation doesn't thrive on Klyuchevskaya's rocky slopes, and the scene appears in shades of gray-a combination of rock, snow, cloud, and volcanic plume. Clouds form a semicircle around the northern half of the volcano, and the volcanic plume blows in the clouds' direction.
Klyuchevskaya (or Kliuchevskoi) is a stratovolcano. It's the highest and most active volcano on Kamchatka. Klyuchevskaya's summit crater has been modified by numerous geologically recent eruptions, including eruptions recorded since the late seventeenth century.
