Contributions to the Study of Lithospheric Deformation and Seismicity in Stable Continental Regions
… recognition of the unique character of deformation and seismicity in stable continental regions (SCRs). However several important questions remain understudied. What controls the locations of earthquakes in SCRs? How well do observations, in SCRs, of elastic strain accumulation and …

The evolution of lithospheric deformation and crustal structure from continental margins to oceanic spreading centers
This thesis investigates the evolution of lithospheric deformation and crustal structure from continental margins to mid-ocean ridges. The first part (Ch. 2) examines the style of segmentation along the U.S. East Coast Margin and investigates the relationship between incipient margin structure and …

Strength envelopes for deforming oceanic lithosphere with some implications for the history of lithospheric deformation of the equatorial Indian Ocean
… (≈27 TN m -1 ) than the force available to drive deformation (9±2 TN m -1 [95% confidence limits]). Thus the strength of oceanic lithosphere is over-estimated. Either pore pressure is much higher than hydrostatic, or the effective coefficient of friction is much lower than found in laboratory …

Three-dimensional thermo-mechanical modeling of deformation at plate boundaries : case study San Andreas Fault System
… geological time scale simulations of lithospheric deformation. The second task consists in the application of the developed tool to the Neogene deformations of the crust and the mantle along the San Andreas Fault System in Central and northern California. The geological time scale …

MANTLE FLOW AND TRANSITION ZONE DISCONTINUITIES BENEATH THE CARRIBEAN PLATE: CONSTRAINTS FROM SHEAR WAVE SPLITTING AND RECEIVER FUNCTION ANALYSES
… wave splitting parameters is used to investigate lithospheric deformation and asthenospheric flow beneath the boundary zone of the North American and Caribbean plates and adjacent areas. A total of 4915 XKS and 1202 pairs of local S wave splitting parameters were obtained at 24 broad band seismic …

The thermal and mechanical structure of stable continental lithosphere within a dynamic mantle
… heat loss system, but also for determining the deformation response of continental lithosphere. This thesis presents the results from numerical simulations and scaling analyses for two studies that solve for: (1) the thermal structure of stable continental lithosphere within a dynamic mantle and …

Tectonic evolution of the Corinth Rift
… provides important constraints on the underlying lithospheric deformation mechanisms, level of seismic hazard and location of likely hydrocarbon traps. The Corinth rift in central Greece is one of the few examples that has experienced a short extensional history (< 5 Myr), has a relatively …

A Geodynamic Investigation of Continental Rifting and Mantle Rheology: Madagascar and East African Rift case studies
… plumesor a superplume in driving surface deformation in the EAR. In chapter 1, we simulate EdgeDriven convection (EDC), constrained by a lithospheric thickness model beneath Madagas-car. The mantle flow associated with the EDC is used to calculate induced olivine aggregates'Lattice …

Seismic studies of 3-D elastic and anelastic structure of crust and upper mantle in Western China
… and strain rates (from GPS), suggests coupled lithospheric deformation in southern Tibet. Notably, the lateral extent of potential megathrust earthquakes may be limited by the segment boundaries. The anelastic structure of the Earth, in particular seismic attenuation, is more useful in …
