Karymsky is one of the most active volcanoes on Russia’s Kamchatka Peninsula. Active for the past 500 years, the volcano regularly emits plumes of ash and volcanic gases. Evidence of these frequent eruptions is visible in this natural-color satellite image. A radial pattern of dark gray ash extends away from Karymsky’s summit, and a plume of ash extends to the southeast, over Kronotskiy Kroniv (Kronotsky Gulf). The image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite on the morning of May 7, 2011.
