Tectonic stress in the southwestern Arabian shield

Engineering Geology, 1986
Abstract Studies of dam sites in the southwestern region of Saudi Arabia gave the opportunity to undertake an in-depth study of the old basement of the Arabian shield. By comparing the results obtained at all scales (seismicity, fracturing of the shield, data on overall tectonics and in-situ measurements) it has been possible to formulate an ...

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

Mapping Tectonic Stress Using Earthquakes

AIP Conference Proceedings, 2005
An earthquakes occurs when the forces acting on a fault overcome its intrinsic strength and cause it to slip abruptly. Understanding more specifically why earthquakes occur at particular locations and times is complicated because in many cases we do not know what these forces actually are, or indeed what processes ultimately trigger slip.

Stress variability and brittle tectonic structures

Earth-Science Reviews, 2005
The problem of stress variability, both in space and time, during brittle deformation of rocks is faced in this note. Several possible causes of the temporal and spatial variations of the stress tensor are reviewed and discussed. A genetic partitioning of the stress tensor is proposed, showing that any stress field within a crustal volume can be seen ...

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),

Tectonic stress distribution of New Zealand

New Zealand is considered as one of the most active earthquake sources in the world, experiencing the deadly 2011 M6.3 at Christchurch, as well as more than 180,000 earthquakes from 1964 to 2016. One important parameter in earthquake statistics is the b value in the frequency magnitude distribution (Gutenberg and Richter, 1954).
