Geodetic data, the spatial and temporal surface expression of complex geophysical processes in the earth, are being acquired today at unprecedented rates and accuracies.  Interferometric synthetic aperture radar (InSAR) is a satellite remote sensing technique used extensively for mapping ground deformation with high spatial resolution and sub-centimeter precision over large areas that is particularly useful for monitoring and analysis of both natural and man-made hazards [Massonnet and Feigl, 1998; Rosen et al., 2000]. Here I present an overview of recent work aimed at improving these measurements and our understanding of the governing processes using standard and advanced InSAR methodologies.  Certain applications of advanced InSAR techniques are designed to minimizing difficulties associated with signal decorrelation [Alipour et al., 2013] while others capable are capable of integrating data from various SAR satellites [Samsonov et al., 2014].  New technologies include those that produce finer resolution images for the generation of more accurate digital elevation models (DEMs) and improved pixel recovery in vegetated or high-relief areas [McKee et al., 2015; Samsonov and Tiampo, 2011].  Case studies are drawn from around the world and include hazards associated with groundwater pumping and subsidence, volcanic activity, earthquakes and induced seismicity [Tiampo et al., 2013, 2015; Samsonov et al., 2014].


Cookies and coffee will be served in the hallway outside S228 starting at 11:45.


Free and open to the public.
