The coulomb stress changes for correlation analysis of tectonic earthquake activity and volcanic of the 2001–2010 Merapi eruption based on focal mechanism data

open access: yesKuwait Journal of Science, 2023
The incident of increased seismic activity of the Merapi volcano was initiated by several tectonic earthquake phenomena. Analysis of the mechanism of tectonic earthquakes can be studied based on the combination of static stress on the rock.

Tectonic stress: Models and magnitudes [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 1980
The combination of plate tectonic models of intraplate stress and observations of the directions of principal midplate stresses provides two types of constraints on the magnitude of deviatoric stress in the lithosphere. First, the fit of global tectonic stress models to observations can constrain stress magnitudes if the magnitude of one of the ...

European continuous active tectonic strain–stress map [PDF]

open access: yesTectonophysics, 2009
This paper shows a new continuous strain-stress map for Europe obtained from the direct inversion of earthquake focal mechanisms calculated from the centroid tensor method. A total of 1608 focal mechanisms have been selected with several quality criteria from different catalogues (CMT Harvard, ETH, Med-Net, I.G.N.

Reconstruction of Tectonic Stresses in Central Sakhalin

open access: yesRussian Journal of Pacific Geology, 2023
The article presents the reconstruction of the tectonic stress field of the central part Sakhalin Island, obtained as a result of field tectonophysical studies in 2020–2022. The measurements made it possible to determine the predominant orientation of the main slickensides systems with different kinematics.

Fingerprinting stress: stylolite and calcite twinning paleopiezometry revealing the complexity of progressive stress patterns during folding-the case of the Monte Nero anticline in the Apennines, Italy [PDF]

open access: yes, 2016
In this study we show for the first time how quantitative stress estimates can be derived by combining calcite twinning and stylolite roughness stress fingerprinting techniques in a fold-and-thrust belt.

Structural and stress analysis in mining practice in the Upper Silesian Coal Basin [PDF]

open access: yes, 2013
The irregular distribution of stress in rock mass is a decisive factor for the origin of rock bursts. Besides, a sound knowledge of stress distribution is very important in the excavation of mine workings. Stress state is affected both by natural stress,

Investigation of Magnetohydrodynamics Technology and It's Application in Tension Drain [PDF]

open access: yesفناوری در مهندسی هوافضا, 2020
The purpose of this paper is to investigate the magnetohydrodynamics technology in creating artificial earthquakes. For this purpose, the possibility of expressing the electronegative mechanism for artificial earthquakes is first discussed.

Normal fault earthquakes or graviquakes [PDF]

open access: yes, 2015
Earthquakes are dissipation of energy throughout elastic waves. Canonically is the elastic energy accumulated during the interseismic period. However, in crustal extensional settings, gravity is the main energy source for hangingwall fault collapsing ...
