The Advanced Rapid Imaging and Analysis (ARIA) Project is a collaboration between JPL and the California Institute of Technology to exploit radar and optical remote sensing, GPS, and seismic observations for hazard science and response.

ARIA investigates the processes and impacts of earthquakes, volcanoes, landslides, fires, subsurface fluid movement, and other natural hazards by combining modern geodesy with ground-based observations to help improve our resilience to such events. The project develops state-of-the-art ground deformation measurement change detection methods and physical models using GPS and synthetic aperture radar observations, automating the required large-scale processing and producing essential data products for the science community.

As populations grow, response to natural disasters becomes an increasingly important link between science and society. We are developing tools to use the growing networks of ground-based GPS sensors and constellations of imaging satellites for hazard monitoring and response. With these new tools, we anticipate the improvement of situational awareness immediately following disasters.
