Spectral element modeling of spontaneous earthquake rupture on rate and state faults: Effect of velocity-strengthening friction at shallow depths
Spectral element modeling spontaneous earthquake rupture rate and state faults:velocity-strengthening friction at shallow depths
2014/4/8
We develop a spectral element method (SEM) for simulating dynamic rupture on rate and state faults and use it to study how the rupture is affected by a shallow fault region of steady state velocity-st...
Variability of earthquake nucleation in continuum models of rate-and-state faults and implications for aftershock rates
Variability earthquake nucleation continuum models rate-and-state faults implications for aftershock rates
2014/4/8
Using two continuum models of rate-and-state faults, one with a weaker patch and the other with rheological transition from steady state velocity-weakening to velocity-strengthening friction, we simul...
Slip rates on the Chelungpu and Chushiang thrust faults inferred from a deformed strath terrace along the Dungpuna river, west central Taiwan
Slip rates on the Chelungpu Chushiang thrust faults a deformed strath terrace along the Dungpuna river west central Taiwan
2014/4/15
The Chelungpu fault produced the September 1999Mw= 7.6 Chi-Chi earthquake,central Taiwan. The shortening rate accommodated by this structure, integrated over several seismic cycles, and its contributi...
DC electric field amplification in the mid-latitude ionosphere over seismically active faults
DC electric field amplification mid-latitude ionosphere seismically active faults
2009/12/28
DC electric field in the ionosphere above seismically active regions can be formed in a process of external current insertion into the atmosphere-ionosphere electric circuit. This current arises as a ...
Non double couple seismic sources,faults interaction and hypothesis of self-organized criticality
couple seismic sources faults interaction self-organized criticality
2009/12/25
Non double couple (NDC) sources are considered in framework of the hypothesis that the process of seismic rupture can be viewed as a result of complicated fault geometry and its segmentation. Analytic...
Temporal clustering of major earthquakes along individual faults due to post-seismic reloading
earthquakes fault models post-seismic rheology viscoelasticity
2014/4/9
Palaeoseismic evidence suggests that earthquake recurrence intervals in some regions can be highly variable, with clusters of multiple large events separated by much longer periods of quiescence. Beca...
Deformation on Nearby Faults Induced by the 1999 Hector Mine Earthquake
Deformation Nearby Faults Hector Mine Earthquake
2014/4/9
Interferometric Synthetic Aperture Radar observations of surface deformation due to the 1999 Hector Mine earthquake reveal motion on several nearby faults of the eastern California shear zone.We docum...
On the use of dislocations to model interseismic strain and stress build-up at intracontinental thrust faults
continental deformation dislocation flexure of the lithosphere seismotectonics
2014/4/15
Creeping dislocations in an elastic half-space are commonly used to model interseismic deformation at subduction zones, and might also apply to major intracontinental thrust faults such as the Main Hi...
Stacking Faults in Kaolin-Group Minerals in the Light of Real Structural Features
Defect structures Dickite Kaolinite Stacking faults X-ray powder diffraction
2012/1/5
A comparison of the structural characteristics of the kaolin-group minerals, mainly kaolinite and dickite, shows that they differ in both the two-dimensional periodicity in the 1:1 layers and the rota...
Stacking Faults in the Kaolin-Group Minerals: Defect Structures of Kaolinite
Crystallinity Defect structure Hinckley index Kaolinite Stacking faults X-ray powder diffraction
2012/1/5
Previous studies of the defect structure of kaolinite have examined samples having a restricted level of defects. This study examined nine kaolinite samples having a large diversity of defect contents...
Qualitative and Quantitative Study of Stacking Faults in a Hydrazine Treated Kaolinite桼elationship with the Infrared Spectra
Qualitative Hydrazine Treated Kaolinite Infrared Spectra
2012/2/13
Artificial stacking faults can be created within a well-crystallized kaolinite by intercalating and removing hydrazine. X-ray powder patterns with electron microscopy show that the created defects are...
