On April 28, 2014, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft acquired this image of Ubinas volcano in the Peruvian Andes. The appearance of a new lava dome in March 2014 and frequent ash emissions are signs of increasing activity at this volcano. The left image depicts vegetation in red, and shows a gray plume streaming south from the summit caldera. The right image is a combination of ASTER thermal infrared bands, highlighting the ash-rich composition of the eruptive plume. The image covers an area of 20 by 37 miles (33 by 60 kilometers), and is located at 16.3 degrees north, 70.9 degrees west.
