|Title||Contemporary crustal deformation in the western Basin and Range, USA|
|Investigator||Bell, John - University of Nevada, Nevada Bureau of Mines and Geology|
|Summary||We propose to use TerraSar-X data to perform InSAR time series analyses and combine the results with GPS data analysis with the objective of measuring surface deformation in the Western Basin and Range province of the western United States. Specific applications in this project are grouped into 1) earthquake information and research, 2) groundwater pumping/aquifer system response, 3) geothermal energy resource evaluation and management, and 4) measurement of three-component secular crustal deformation with integrated InSAR and GPS data. InSAR has been previously shown to be an effective tool for quantifying and modeling the surface deformation associated with earthquake activity in the Basin and Range. In addition, active crustal deformation has been correlated with geothermal resource occurrence, and this project will extend the use of InSAR in groundwater aquifer studies to identifying and modeling geothermal reservoir response to hydrothermal fluid migration.
The project team has extensive previous experience in applying InSAR analyses to contemporary crustal deformation studies in the Basin and Range. Investigators John W. Bell and William C. Hammond at the University of Nevada will lead the project. Additional co-investigators from other research institutions will contribute to specific elements of the study as the project progresses.
This project will utilize archived TerraSar-X StripMap data from within the boundaries of the specified geographic location: 38-42 degrees North latitude, 117-121 degrees West longitude. InSAR processing will use both ascending and descending satellite tracks and single or dual polarization. The archives currently contain more than 80 StripMap scenes within the proposed study area. This project will request access to these archived data and to future data once the 18 month archive threshold is met. A total of 200 scenes over the duration of the project is requested.
The study will be supported from in-house research resources at the University of Nevada, and in part from a research seed grant from the U.S. Department of Energy. InSAR processing will be done in-house using computational resources available in the Nevada Geodetic Laboratory and NASA InSAR Laboratory, both in the Nevada Bureau of Mines and Geology at the University of Nevada.
Anticipated results include: 1. achieving better coherence and persistent target resolution than previous studies utilizing C-band and L-band radar, 2. capability to combine TerraSar-X time series data with co-located GPS time series, 3. capability to differentiate tectonic, groundwater pumping, and geothermal production deformations signals.
