This false-color image of Peru's Ubinas volcano was acquired on April 14, 2014, by NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR. Located about 100 miles (160 kilometers) from the city of Arequipa, Ubinas is Peru's most active volcano.
UAVSAR flew exactly the same flight path over Ubinas in 2013. By combining the images from the two years, researchers will produce detailed maps of surface motions that can improve models of volcanic deformation.
