Tectonic Stress Reconstruction Based on Structural Features in Tectonic Superposition Areas

Mining, Metallurgy & Exploration, 2020
Tectonic stress is an important parameter for understanding the dynamics of underground engineering and for the exploitation of coalbed methane. Multiple-period structural features usually have complex spatial relationships in tectonic superposition areas, which provides evidence for identification of the sequence of the tectonic stress period ...

Tectonic stress in the Earth’s crust: advances in the World Stress Map project

Geological Society, London, Special Publications, 2003
Abstract Tectonic stress is one of the fundamental data sets in Earth sciences comparable with topography, gravity, heat flow and others. The importance of stress observations for both academic research (e.g. geodynamics, plate tectonics) and applied sciences (e.g.

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 ...

Earthquake Stress Drops, Ambient Tectonic Stresses and Stresses That Drive Plate Motions

pure and applied geophysics, 1977
A variety of geophysical observations suggests that the upper portion of the lithosphere, herein referred to as the elastic plate, has long-term material properties and frictional strength significantly greater than the lower lithosphere. If the average frictional stress along the non-ridge margin of the elastic plate is of the order of a kilobar, as ...

Late Aftershocks, Tectonic Stress and Dilatancy

Nature, 1973
THE focal mechanisms of micro-aftershocks occurring 3.5 yr after the Inangahua (New Zealand) earthquake of May 23, 1968 (magnitude 7.1), differ drastically from those of the main shock and early aftershocks and are in apparent conflict with the known tectonic stress.

Stress measurements and tectonic implications for Fennoscandia

Tectonophysics, 1991
Abstract The main results from the Fennoscandian Rock Stress Data Base (FRSDB) are presented. Rock stress data from Sweden are now being selected to enter the data base of the World Stress Map Project of the International Lithosphere Programme. It is suggested that ridge push from the Mid-Atlantic Ridge is the major stress-generating mechanism.

Seismic activation of tectonic stresses by mining

Journal of Seismology, 2013
Hard coal mining in the area of the Bytom Syncline (Upper Silesia Coal Basin, Poland) has been associated with the occurrence of high-energy seismic events (up to 109 J; local magnitude up to 4.0), which have been recorded by the local mining seismological network and regional seismological network. It has been noticed that the strongest seismic events

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.

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),
