Tectonic stress field in the Indian subcontinent

Journal of Geophysical Research: Solid Earth, 1992
A map of maximum horizontal compressive stress orientation in the Indian subcontinent has been prepared using orientations derived from three different stress indicators: borehole elongation breakouts, in situ hydraulic fracturing measurements, and earthquake focal mechanisms. Most part of the subcontinent appears to be characterized by a compressional

Numerical Simulation of Tectonic Stress Field in Longmenshan Tectonic Belts after Earthquake

Applied Mechanics and Materials, 2012
Two-dimensional finite element model of Longmenshan area was built on the basis of depth study on geological structure conditions and of rock mechanical properties in Longmenshan area, tectonic stress field and variation process of Longmenshan fault belt were inversed after the earthquake.

Modern tectonic stress field in Southwest Yunnan, China

Acta Seismologica Sinica, 2001
By means of inversion of fault slip data, the parameters of 20 tectonic stress tensors in Southwest Yunnan region are determined. Compared with the average stress field of the region obtained from focal mechanism solutions, the following characteristics of modern tectonic stress field in this region are obtained.

Tectonic Stress Fields and Karst

2014
Many natural causes exist controlling the formation of fractures. The rock properties relating to the brittleness is one of the most important of them for the variations in natural fracture density. These properties may vary from regional to local scale; they may vary significantly within the rock formations and between formations.

Tectonic stress field in East Eurasia

Physics of the Earth and Planetary Interiors, 1983
Abstract The overall pattern of the recent tectonic stress field in the eastern part of the Eurasian plate is inferred from the geological features of large transcurrent and reverse faults, graben structures and from focal mechanism solutions of shallow earthquakes. NE-SW striking trajectory lines, of maximum horizontal tectonic stress axis (σ Hmax),

Modern tectonic stress field deeply in Xuzhou Coal Mine

Journal of Coal Science and Engineering (China), 2013
By inverting fault slip data, the parameters of 12 tectonic stress tensors in the mine region can be determined. The following characteristics can be obtained for recent tectonic stress fields, which are found deep in the study region. The results show that the recent tectonic stress field mainly presents the characteristics of near NWW-SSE maximum ...
