Abstract We present new Interferometric Synthetic Aperture Radar (InSAR) observations of surface deformation in the Altiplano–Puna region (South America) where previous studies documented a broad uplift at an average rate of ∼10 mm/yr. We use data from the Sentinel-1 satellite mission to produce high-resolution velocity maps and time series of surface displacements between years 2014–2017. The data reveal that the uplift has slowed down substantially compared to the 1992–2010 epoch and is charac...

Author(s): Tymofyeyeva, Ekaterina | Advisor(s): Fialko, Yuri A | Abstract: In this dissertation, I present a method for improving the accuracy of Interferometric Synthetic Aperture Radar (InSAR) measurements of crustal deformation by reducing the impact of atmospheric propagation delays on the radar phase. The proposed technique (CANDIS) is based on the idea of common scene stacking, which takes advantage of the fact that interferograms that share a common scene also share the same atmospheric c...

The Cerro Prieto geothermal field (CPGF) lies at the step-over between the imperial and the Cerro Prieto faults in northern Baja California, Mexico. While tectonically this is the most active section of the southern San Andreas Fault system, the spatial and temporal deformation in the area is poorly resolved by the sparse global positioning system (GPS) network coverage. Moreover, interferograms from satellite observations spanning more than a few months are decorrelated due to the extensive agr...

We present a method for estimating radar phase delays due to propagation through the troposphere and the ionosphere based on the averaging of redundant interferograms that share a common scene. Estimated atmospheric contributions can then be subtracted from the radar interferograms to improve measurements of surface deformation. Inversions using synthetic data demonstrate that this procedure can considerably reduce scatter in the time series of the line-of-sight displacements. We demonstrate the...
