Tectonic stress in the plates
TLDR
In this article, the basic set of global intraplate stress orientation data is plotted and tabulated, and several large-scale patterns can be seen, such as the E-W to NE-SW trend for the maximum compressive stress.Abstract:
In the present paper, the basic set of global intraplate stress orientation data is plotted and tabulated. Although the global intraplate stress field is complicated, several large-scale patterns can be seen. Much of stable North America is characterized by an E-W to NE-SW trend for the maximum compressive stress. South American lithosphere beneath the Andes, and perhaps farther east in the stable interior, has horizontal compressive stresses trending E-W to NW-SE. Western Europe north of the Alps is characterized by a NW-SE trending maximum horizontal compression, while Asia has the maximum horizontal compressive stress trending more nearly N-S, especially near the Himalayan front.read more

First‐ and second‐order patterns of stress in the lithosphere: The World Stress Map Project
TL;DR: In this paper, more than 7300 in situ stress orientations have been compiled as part of the World Stress Map project and over 4400 are considered reliable tectonic stress indicators, recording horizontal stress orientation to within <±25°.

Focal depths of intracontinental and intraplate earthquakes and their implications for the thermal and mechanical properties of the lithosphere
Wang-Ping Chen,Peter Molnar +1 more
TL;DR: In this article, the authors investigate the distribution of focal depths for earthquakes that do not appear to be associated with zones of recent subduction, using both new results from analyses of individual events recorded at teleseismic distances and published data for both microearthquakes and larger events.

Relations among subduction parameters
TL;DR: In this article, a multivariate analysis is applied to this data set to isolate causal relationships among these parameters, which yields empirical quantitative relations that predict strain regime and strike-slip faulting in the overriding plate.

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.

The dynamics of cenozoic and mesozoic plate motions
TL;DR: In this article, the authors investigate the kinematics of the last 120 Myr of plate motions and the dynamics of Cenozoic motions, paying special attention to changes in the character of plate motion and plate-driving forces.

Theoretical basis of some empirical relations in seismology
Hiroo Kanamori,Don L. Anderson +1 more
TL;DR: In this article, an empirical relation involving seismic moment M, energy E, magnitude M, and fault dimension L (or area S) is discussed on the basis of an extensive set of earthquake data (M_S ≧ 6) and simple crack and dynamic dislocation models.
Present-day plate motions
TL;DR: A data set comprising 110 spreading rates, 78 transform fault azimuths, and 142 earthquake slip vectors has been inverted to yield a new instantaneous plate motion model, designated Relative Motion 2 (RM2).

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.
