Synthesis of geodetic and seismological results for the 1979 Imperial Valley earthquake is approached using three-dimensional finite element modeling techniques. The displacements and stresses are calculated elastically throughout the modeled region. The vertical elastic structure in the model is derived from compressional and shear wave velocities as used in the seismic data analysis (Fuis et ...

fault zones and fault-related fracture systems control the mechanical behaviors and fluid-flow properties of the earth’s crust. furthermore, nowadays, modeling is being increasingly used in order to understand the behavior of rock masses, and to determine their characteristics. in this work, fault zones and fracture patterns are reviewed, and also comprehensive studies are carried out on the fr...

A generalized Markov chain representation of fault dynamics is presented for the case that available modeling of fault growth physics and future environmental stresses can be represented by two independent stochastic process models. A contrived but representatively challenging example will be presented and analyzed, in which uncertainty in the modeling of fault growth physics is represented by ...

[1] The massive tsunami generated by the 11 March 2011 Tohoku earthquake (Mw 9.0) was widely recorded by GPS buoys, wave gauges, and ocean bottom pressure sensors around the source. Numerous inversions for finite‐fault slip time histories have been performed using seismic and/ or geodetic observations, yielding generally consistent patterns of large co‐seismic slip offshore near the hypocenter ...

We present various techniques to visualize timevarying, 3D earthquake modeling datasets. We use RIVA (Remote Interactive Visualization and Analysis) to visualize the surface deformation as a synthetic interferogram overlaid on top of a high resolution LandSAT image and digital terrain. We use ParVox (PARallel VOXel Renderer) to visualize the simulated normal stress and shear stress along the No...

This research is based on the modeling of co-seismic deformations due to the fault movement in the elastic environments, and we can obtain the deformations generated in the faults. Here, modeling of the co-seismic displacement field is based on the analytical method with two spherical dislocation model and half-space dislocation model. The difference in displacement field from two spherical and...

[1] What happens in the crust as a result of geodetically observed secular motions? In this paper we find out by distorting a finite element model of California using GPS-derived displacements. A complex model was constructed using spatially varying crustal thickness, geothermal gradient, topography, and creeping faults. GPS velocity observations were interpolated and extrapolated across the mo...
