TLDR
In this article, the authors used regional patterns of present-day tectonic stress to evaluate the forces acting on the lithosphere and to investigate intraplate seismicity, and found that most intraplate regions are characterized by a compressional stress regime; extension is limited almost entirely to thermally uplifted regions.Abstract:
Regional patterns of present-day tectonic stress can be used to evaluate the forces acting on the lithosphere and to investigate intraplate seismicity. Most intraplate regions are characterized by a compressional stress regime; extension is limited almost entirely to thermally uplifted regions. In several plates the maximum horizontal stress is subparallel to the direction of absolute plate motion, suggesting that the forces driving the plates also dominate the stress distribution in the plate interior.read more

The Bend: Origin and significance
TL;DR: The origin of the bend in the Hawaiian-Emperor seamount chain is the prototypical problem at the heart of the ongoing hotspot debate: Does the bend represent a change in motion between the Pacific plate and underlying hotspot (plume?), or might it represent a changing in the intraplate stress field? as discussed by the authors.

The stress field in the frontal part of the Eastern Alps (Austria) from borehole image log data
TL;DR: In this paper, the authors inferred in-situ stress orientations in the frontal part of the Eastern Alps from borehole breakouts and drilling-induced tensile fractures depicted in image logs from 62 vertical or slightly deviated wellbores with up to 5 km depth.

Joint inversion of the kinematics and dynamics of the North American plate
Shimin Wang,Ren Wang +1 more
TL;DR: In this paper, a finite element model is presented to study the kinematics and dynamics of the North American plate, where the plate is represented by a portion of thin spherical shell modeled with Newtonian fluid and the external actions acting at the plate boundary as well as on the plate bottom are expressed by a set of undetermined parameters.

The mechanism of faulting regimes change over depths in the sedimentary layers in an intracratonic basin
Xuejun Zhou,Thomas J. Burbey +1 more
TL;DR: In this paper, numerical simulation is used to characterize the Illinois Basin in North America, and the simulation results show that a thrust-faulting regime is expected at shallow depths, while the three principal stresses are close in magnitude at intermediate depths.

In-Situ Stress and Fracture Controls on Permeability Distribution within Walloon Subgroup, Surat Basin
TL;DR: In this paper, the spatial and stratigraphic variability of stress and fracture orientation relative to measured permeability within the Walloon Subgroup (WSG) that hosts CSG resources within the Surat Basin was investigated.

An analysis of the variation of ocean floor bathymetry and heat flow with age
Barry Parsons,John G. Sclater +1 more
TL;DR: In this paper, a simple cooling model and the plate model were proposed to account for the variation in depth and heat flow with increasing age of the ocean floor. But the results were limited to the North Pacific and North Atlantic basins.
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).

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.
