Ambient tectonic stress as fragile geological feature [PDF]

Geochemistry, Geophysics, Geosystems, 2014
Strong seismic waves produce frictional failure within shallow pervasively cracked rocks. Distributed failure preferentially relaxes ambient tectonic stresses, providing a fragility measure of past strong shaking. Relaxation of the regional fault-normal compression appears to have occurred within granite from 768 m down to ∼1000–1600 m depth at the ...

Tectonic evolution of a continental collision zone: A thermomechanical numerical model [PDF]

, 2004
We model evolution of a continent-continent collision and draw some parallels with the tectonic evolution of the Himalaya. We use a large-scale visco-plasto-elastic thermomechanical model that has a free upper surface, accounts for erosion and deposition

Earthquakes: from chemical alteration to mechanical rupture

, 1998
In the standard rebound theory of earthquakes, elastic deformation energy is progressively stored in the crust until a threshold is reached at which it is suddenly released in an earthquake.

Remote-sensing of tectonic-induced stress across faults using high energy muon beams

Physical Review Research
We illustrate a theoretical study of a technique using high-energy muon beams (TeV class) propagating through thick (kilometer-long) crystalline rock layers subject to tectonic-induced stress, potentially capable of actively monitoring the temporal ...

Simulation of a Multi-Stage Stress Field and Regional Prediction of Structural Fractures in the Tucheng Syncline, Western Guizhou, China

Geosciences
The prediction of structural fractures in concealed coal-bearing strata has always been a complex problem. The purpose of this study was to clarify the tectonic evolution of the study area, i.e., the Tucheng syncline, since the coal-forming period and to

Multiple Linear Regression Inversion of the Ground Stress Field in Rock Masses for Tunnel Engineering: A Novel Approach to Stress Field Reconstruction

Buildings
The inversion of the ground stress field in rock masses is critical for accurate tunnel and underground engineering design. This study addresses the challenge of accurately capturing both the primary and secondary stress field components in rock masses ...

Recent Seismic Activity in the Azores Region [PDF]

, 2008
This seismic activity in the Azores Region is characterized by sequences of low-magnitude events, usually with epicenter off-shore. These seismic sequences are sometimes triggered by larger events, felt by the population, that could produce significant ...

In-situ stress distribution model in viscoelastic coal seams based on the stress relaxation effects and its application in outburst-prone coal seams

Meitan xuebao
In-situ stress is a core factor controlling dynamic gas disasters in coal mines. Existing in-situ stress models are primarily based on the elastic properties of coal-rock formations and are not suitable for viscoelastic coal media.
