This false-color image of Colombia's Galeras Volcano, was acquired by UAVSAR on March 13, 2013. A highly active volcano, Galeras features a breached caldera and an active cone that produces numerous small to moderate explosive eruptions. It is located immediately west of the city of Pasto. UAVSAR will precisely fly the same flight path over the volcano in 2014. By comparing these camera-like images taken at different times, interferograms are generated that reveal changes in Earth's surface caused by volcanic deformation.

UAVSAR is part of NASA's ongoing effort to apply space-based technologies, ground-based techniques and complex computer models to advance our understanding of Earth deformation processes, such as those caused by earthquakes, volcanoes and landslides. UAVSAR is also serving as a flying test bed to evaluate the tools and technologies for future space-based radars, such as those planned for a NASA Synthetic Aperture Radar (SAR) mission currently in formulation. That mission will study hazards such as earthquakes, volcanoes and landslides, as well as global environmental change.
