NASA's Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) acquired this image of Peru's Sabancaya stratovolcano on April 10, 2019. Sabancaya has been erupting regularly for several months, sending ash plumes high into the air. At the time this image was taken, the plume reached an altitude of 9100 meters (9950 yards) and was moving southeastward. In the left image, Sabancaya is under the bright round white cloud. The greyish clouds to the southeast are ash plumes. The Ampato volcano, with its prominent summit caldera, is to the south. The red areas are vegetation. The right thermal image shows the plume in purple, indicating that it is dominantly composed of sulfur dioxide gas. A bright hotspot can be seen directly north of the black (cold) cloud over Sabancaya. The image covers an area of 19.5 by 17.2 kilometers (12 miles by 11 miles), and is located at 15.8 degrees south, 71.9 degrees west. https://photojournal.jpl.nasa.gov/catalog/PIA23143
