Insights into fundamental problems of rockburst under the modern structure stress field

open access: yesScientific Reports, 2022
Rockbursts are some of the most severe dynamic disasters in coal mines. In this paper, the discrimination method of the tectonic stress field is proposed by analyzing the modern stress field in China.

Influence of preexisting structures on the variation of neotectonic paleostress orientation in an area of the Southeastern Brazilian Margin

open access: yesBrazilian Journal of Geology, 2021
The Southeastern Brazilian Margin presents a NE-SW-striking structural framework, which is characteristic of the Neoproterozoic Ribeira Belt. Other important structural trends along the area are associated with E-W and NW-SE-striking structures, being ...

Recent Tectonic Stress Field in Northwest Yunnan Province

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract Based on the collected focal mechanism solutions of M≥3.0 earthquakes in Northwest Yunnan from 2000 to 2018, we used Michael’s linear inversion method to perform stress tensor inversion, and attempted to analyze the temporal and spatial evolution characteristics of the tectonic stress field in Northwest Yunnan.

The Theory of Stress Wave Radiation from Explosions in Prestressed Media [PDF]

open access: yes, 1972
Stress wave radiation from underground explosions has been observed to contain an anomalous shear wave contribution which is most likely of tectonic origin.

Present-day stress orientations and tectonic provinces of the NW Borneo collisional margin [PDF]

open access: yes, 2010
Extent: 15p.Borehole failure observed on image and dipmeter logs from 55 petroleum wells across the NW Borneo collisional margin were used to determine maximum horizontal stress (σH) orientations; combined with seismic and outcrop data, they define seven

An integrated geodetic and InSAR technique for the monitoring and detection of active faulting in southwestern Sicily [PDF]

open access: yes, 2020
We present the results of the analysis of GNSS (Global Navigation Satellite System) and InSAR (Interferometric synthetic-aperture radar) data collected in the frame of a project financed by the “Struttura Terremoti” of INGV (Istituto Nazionale di ...

Simulation of tectonic stress field and prediction of tectonic fracture distribution in Longmaxi Formation in Lintanchang area of eastern Sichuan Basin

open access: yesFrontiers in Earth Science, 2022
Shale is a low-porosity and low-permeability reservoir, and structural fractures are the main controlling factor for the migration and accumulation of shale gas. Moreover, tectonic fractures are controlled by the paleo-tectonic stress field.

On STEM of tectonic stress fields in tsunami regions [PDF]

open access: yesWIT Transactions on Modelling and Simulation, 2011
We apply the STEM (Stress Trajectories Element Method) to investigate changes in the stress states as a result of a great earthquake. Two regions are considered: 1) the region affected by the great Sumatran earthquake (26 of December 2004, 9.1M), taking into account data collected before and after the event separately; 2) the region where the recent ...
