Activity on Anatahan
This page contains archived content and is no longer being updated.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.
On March 5, 2008, the plume from the Anatahan Volcano appeared to intensify. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite took this picture the same day. One day earlier, the plume blew away from the volcano toward the northeast. On March 5, the plume hovered over the volcano’s summit, thick enough to completely hide the volcanic island from view. The plume’s position in this image could result from a wind shift, or a burst of volcanic activity shortly before the satellite passed overhead.
