Activity at Kizimen Volcano
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
An ash and steam plume from Kizimen Volcano streams over the icy waters of Kamchatskiy Zaliv (the Gulf of Kamchatka) on the afternoon of February 1, 2011. At the time, the U.S. Air Force weather service reported ash at an altitude of 11,000 feet (3,400 meters). The current eruption of Kizimen is both explosive—violent emissions of ash and rock—and effusive—lava flows spilling from the volcano’s summit onto its upper flanks. This natural-color image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua satellite.
