The Saghand area is underlain by rocks comprising a part of the Central Iranian continental terrane. The Central Iranian terrane records a prolonged history of fragmentation, drift, collision and amalgamation, which reflects the tectonic development of the Alpine-Himalayan oroge…

Enhancement methods applied on various satellite images (ASTER, ETM and RADAR SAT-1) facilitated the identification and mapping of tectonic fractures in the Zagros fold-and-thrust belt in southwest Iran. The results of the fracture analysis on these enhanced images reveal four p…
Paleoseismologic trenches excavated across the North Anatolian fault in Turkey are used to characterize the spatial-temporal pattern of seismic moment release on this plate-bounding strike-slip fault. Trenches at Alayurt reveal evidence for at least four (possibly five) surface …
This work utilizes the Four-Dimensional Plates (4DPlates) software, and Differential Interferometric Synthetic Aperture Radar (DInSAR) to examine plate-scale, regional-scale and local-scale kinematics of the Afro-Arabian Rift System with emphasis on the Afar Depression in Ethiop…
The deformation of a plate due to boundary stresses is investigated using both the elastic and viscous models for plate deformation. The role of basal shear stress (at the lithosphere-asthenosphere boundary), oblique convergence and strength inhomogeneity are investigated for mo…
Identification and characterization of the Paleozoic Suwanee basin sedimentary sequence and the associated Pangea supercontinent transcurrent fault are critical in furthering our present understanding of tectonic history and its impacts today. However, explicit bounding of the S…
Seismologists use the seismic wavefield to image the Earth’s structure at a wide range of scales, from a few meters to 1000s of km. Sources (earthquakes, explosions, etc.) of seismic waves can also be located and distinguished using the seismic wavefield. In this dissertation, I…
Since the Mesozoic, the west coast of North America has experienced near continuous right-lateral shear. Over this time, a series of exotic crustal terranes accreted to and translated along the expanding westward edge of the continent. In this dissertation, I use low-temperature…
This thesis focuses on determining how forearc strain was and is accommodated by ancient and active faults in the northern forearc of the Cascadia subduction zone on southern Vancouver Island, Canada. By examining these faults, permanent forearc strain can be resolved, helping u…
