Detection, Containment And Scaling Relations Of Near Source Explosionsin Granite Through Moment Tensor Representations, Mason Macphail
Earth Sciences Theses and Dissertations
The Source Phenomenology Experiment (SPE) was a series of nine, single-fired chemical explosions within the Morenci Copper mine in Arizona. Its purpose was to design, detonate, record and analyze seismic waveforms from these single-fired, partially and fully contained explosions. Ground motion data from the SPE are analyzed in this study to assess the uniqueness of the source representation of these explosions and its ability to resolve yield and depth when containment and geology or physical parameters of the source region may have a range of possible values. The P-wave velocities (Vp) at the test site are well constrained …
Determining Principal Stress Orientations And Magnitudes In The Fort Worth Basin, Texas, Louis Quinones
Determining Principal Stress Orientations And Magnitudes In The Fort Worth Basin, Texas, Louis Quinones
Earth Sciences Theses and Dissertations
Since 2008, the Fort Worth Basin in northern Texas has experienced over 30 M3.0+ earthquakes, including one M4.0. Earthquakes have primarily occurred on Precambrian basement faults and within the overlying Ellenburger limestone unit, which is the primary wastewater disposal formation used in the basin. The most productive earthquake sequences (Azle, Irving- Dallas, and Venus) have been recorded using local seismic networks containing a mix of SMU broadband, IRIS short period, and USGS NetQuakes stations and by regional seismic networks operated under the Advanced National Seismic System and the Texas Seismic Network (TexNet).
Using the data recorded by the local seismic …
Characterization Of Ground Deformation Associated With Shallow Groundwater Processes Using Satellite Radar Interferometry, Xie Hu
Earth Sciences Theses and Dissertations
Shallow groundwater processes maylead to ground deformation and even geohazards. With the features of day-and-night accessibility and large-scale coverage, time-series interferometric synthetic aperture radar (InSAR) has proven a useful tool for mapping the deformation over various landscapes at cm to mm level with weekly to monthly updates. However, it has limitations such as, decorrelation,atmospheric artifacts, topographic errors, andunwrapping errors, in particular for the hilly, vegetated, and complicated deformation patterns. In this dissertation, I focus on characterizing the ground deformation over landslides, aquifer systems, and mine tailings impoundment, using the designed advanced time-series InSAR strategy, as well as theinterdisciplinary knowledge of …
