JPL-Caltech responded to Hurricane Maria by creating Damage Proxy Maps (DPMs) depicting areas in Puerto Rico and the Commonwealth of Dominica likely damaged by the Hurricane. More details can be found here.

JPL-Caltech produced a map of damage in and around Mexico City from the Sept. 19, 2017, magnitude 7.1 Raboso earthquake, based on ground and building surface changes detected by ESA satellites. Color variations from yellow to red indicate increasingly more significant ground surface change. More details can be found here.

JPL-Caltech created this Damage Proxy Map (DPM) depicting areas of Southwestern Florida that were likely damaged (red and yellow pixels) as a result of Hurricane Irma. More details can be found here.

JPL-Caltech in collaboration with ASI/CIDOT responded to the M6.0 earthquake in California's Napa Valley by generating rapid GPS and SAR products, including radar based deformation and damage maps. More details and links to products can be found here.

[1] The Damage Proxy Map (DPM) indicates centimeter scale change due to subsidence, inundation, or structure collapse allowing early assessment of the scale of damage. [2] Re-zoning map indicating where repair and rebuilding will be allowed.  This map is the product of many man-hours of effort to assess structures and the land that they were built on.


ARIA is a collaboration between JPL and Caltech to exploit radar and optical remote sensing, GPS, and seismic observations for hazard science and response. 


Science & Research

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

Monitoring & Response

As populations grow, response to natural disasters is becoming an increasingly important part of 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.
