TLDR
In this paper, the authors computed the stress induced by the topography and density heterogeneity in the lithosphere for two different tectonic regions of the North American plate and showed that these stresses are locally comparable in magnitude to the regional tectonics stress (~ 20-50 MPa).About:

The effective elastic thickness (Te) of continental lithosphere: What does it really mean?
Evgene B. Burov,Michel Diament +1 more
TL;DR: In this paper, the authors developed an analytical and numerical approach that allows direct treatment of Te in terms of the lithospheric rheology, thermal structure, and strain/stress distribution.

Stress field constraints on intraplate seismicity in eastern North America
TL;DR: In this article, the authors used in situ stress orientations from well bore breakout and hydraulic fracturing data to determine if slip is compatible with a broad-scale regional stress field derived from plate-driving forces and, if so, under what conditions (stress regime, pore pressure, and frictional coefficient).

The effect of topography on the state of stress in the crust: Application to the site of the Cajon Pass Scientific Drilling Project
Lanbo Liu,Mark D. Zoback +1 more
TL;DR: In this article, a generalized approximate method for assessing the effect of topography on the state of stress at depth in the crust and applies it to the site of the Cajon Pass Scientific Drilling Project.

Large-scale crustal heterogeneities and lithospheric strength in cratons
TL;DR: In this article, the authors used forward models to account for lateral variations in mechanical properties and their effect on the equivalent elastic thickness (EET) of the continental lithosphere, and calculated the strain/stress distributions and displacement fields.

Maximum horizontal stress orientations in the Cooper Basin, Australia: implications for plate-scale tectonics and local stress sources
TL;DR: In this article, the average east-west maximum horizontal stress orientation in the Cooper Basin indicates that stresses from tensional forces acting along the Tonga-Kermadec subduction zone are not transmitted into the interior of the Australian plate.

Implications of Plate Tectonics for the Cenozoic Tectonic Evolution of Western North America
TL;DR: In this paper, the authors examined the history of plate motions between the American and Pacific plates in the late Cenozoic and found that the two plates were fixed with respect to one another until 5 m.y.

On the Relative Importance of the Driving Forces of Plate Motion
Donald W. Forsyth,Seiya Uyedaf +1 more
TL;DR: In this paper, the relative strength of the plausible driving forces, given the observed motions and geometries of the lithospheric plates, was analyzed. But the results indicate that the forces acting on the downgoing slab control the velocity of the oceanic plates and are an order of magnitude stronger than any other force.

State of stress in the conterminous United States
Mary Lou Zoback,Mark D. Zoback +1 more
TL;DR: In this article, a major variation in principal stress orientation is observed between the Atlantic Coast and mid-continent areas, and the authors suggest that these transitions can be abrupt, occurring over <75 km in places.

Stresses in the lithosphere caused by crustal thickness inhomogeneities
TL;DR: A physical analysis of the earth's lithosphere floating on the asthenosphere is given in this paper, where the main stresses are caused by regional and global crustal thickness inhomogeneities.

Tectonics and topography for a lithosphere containing density heterogeneities
Luce Fleitout,Claude Froidevaux +1 more
TL;DR: In this paper, the role of lithospheric density heterogeneities with respect to mountain building and other processes of intraplate deformation has been clarified, and the analytical treatment is based on Fourier transform.
