False-color image of Colombia's highly active Galeras Volcano, acquired by NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) on March 13, 2013,
This false-color image of Colombia’s highly active Galeras Volcano, acquired by NASA’s Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) on March 13, 2013, detailed a breached caldera and an active cone that produced numerous small to moderate explosive eruptions. By comparing these camera-like images taken at different times, interferograms are generated that reveal changes in Earth’s surface caused by volcanic deformation. NASA’s C-20A environmental research aircraft carrying the UAVSAR flew the same flight path precisely over the volcano in 2014.March 13, 2013
