Ash spewed miles high from this stratovolcano on Russia’s Kamchatka Peninsula. View from Terra & Aqua.

View Image Comparison View Both Images Kizimen, an isolated stratovolcano on Russia’s Kamchatka Peninsula, spewed ash nearly 10 kilometers (32,800 feet) into the air in mid-December 2011. Seismic activity and thermal anomalies increased near the volcano in early December, culminating in a fresh eruption starting on December 13. Kizimen has been erupting sporadically since 2009. The Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on NASA’s Terra and Aqua satellites captured these natural-color images on December 14, 2011. Terra passed over far eastern Russia first, at 11:05 a.m. local time, with Aqua following one hour and 50 minutes later. The time difference afforded a view of the movement of the ash plume as it blew to the south and east. Observers with the Kamchatkan Volcanic Eruption Response Team detected lava flows and pyroclastic flows (hot avalanc...
