The Ubinas Volcano in Peru released another plume of ash and/or steam on August 12, 2006. The Moderate Resolution Imaging Spectroradiometer (MODIS) flying onboard NASA’s Terra satellite took this picture the same day. This plume remained intact for a distance of approximately 100 kilometers as it traveled toward the southeast. In this picture, the plume appears as a slightly dingy mass. A denser puffball of volcanic material over the volcano’s summit, as well as a similarly dense mass in the southeast, suggests that the volcano released its plume in strong spurts interspersed with fainter emissions. In contrast to the plume, clouds appear bright white and opaque. Lake Titicaca appears in the northeast corner of the image.
