Klyuchevskaya Sopka eruption, 16 November 2013

This photograph provides a view of an eruption plume emanating from Kliuchevskoi, one of the many active volcanoes on the Kamchatka Peninsula. The image was taken when the ISS was located over a ground position more than 1,500 kilometers to the southwest.
The plume—likely a combination of steam, volcanic gases, and ash—stretched to the east-southeast due to prevailing winds. The dark region to the north-northwest is likely a product of shadows and of ash settling out. Several other volcanoes are visible in the image, including Ushkovsky, Tolbachik, Zimina, and Udina. To the south-southwest of Kliuchevskoi lies Bezymianny Volcano, which appears to be emitting a small steam plume (at image center).
