Shiveluch, one of largest and most active volcanoes on Russia’s Kamchatka Peninsula, continued activity in February 2015 with explosive events toward the end of the month.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra (top) and Aqua (middle) satellites acquired these images of ash from the volcano on February 28, 2015. The images together, acquired 10 minutes apart, show the ash advancing toward the northeast (bottom).
According to the Kamchatka Volcanic Emergency Response Team (KVERT), the volcanic plume on February 28 reached an altitude of almost 9,000 meters (30,000 feet). News reports say that the ash ultimately made it across the Bering Sea into western Alaska, where it disrupted air travel.
