The Soufriere Hills Volcano on Montserrat produced a faint but steady plume of ash on September 4-5, 2005. The Moderate Resolution Imaging Spectroradiometer (MODIS) flying onboard the Aqua satellite took this picture on September 5. In this image, a thin plume of volcanic ash drifts westward from the volcano, and red lines outline the volcano’s summit. The volcanic ash appears as a lighter shade of blue over the ocean surface while the clouds are white. To the northwest of Montserrat, partially obscured by clouds, are the islands of St. Kitts and Nevis.
