Mani Earthquake, occurred on Nov. 8, 1997 in Tibet, China, is the strongest event in China since 90’s in 20 century. Investigation and research of its principle and geometry, dynamics related to surface rupture zone is very significant to analyze the development and evolution of China’s earthquake in the future. In this study, we investigate the distribution of surface deformation and extract d...

Time series analysis of interferometric synthetic aperture radar data reveals coseismic and postseismic surface displacements associated with the 2007 M5.5 earthquake along the southern Ghazaband fault, a major but little studied fault in Pakistan. Modeling indicates that the coseismic surface deformation was caused by ~9 cm of strike-slip displacement along a shallow subvertical fault. The ear...

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...

Evaluating the transfer of stresses from megathrust earthquakes to adjacent segments is fundamental assess seismic hazard. Here, we use a 3D forward model as well GPS and data investigate transient deformation Coulomb Failure Stresses (CFS) changes induced by 2010 Maule earthquake in its northern segment, where Mw 8.3 Illapel occurred 2015. The incorporates coseismically instantaneous, elastic ...

Continuously recording Global Positioning System stations near the 28 March 2005 rupture of the Sunda megathrust [moment magnitude (Mw) 8.7] show that the earthquake triggered aseismic frictional afterslip on the subduction megathrust, with a major fraction of this slip in the up-dip direction from the main rupture. Eleven months after the main shock, afterslip continues at rates several times ...

High-rise flexible-frame buildings are commonly considered to be resistant to shaking from the largest earthquakes. In addition, base isolation has become increasingly popular for critical buildings that should still function after an earthquake. How will these two types of buildings perform if a large earthquake occurs beneath a metropolitan area? To answer this question, we simulated the near...

This paper presents a study on the permanent lateral deformation and potential flow of ground due to soil liquefaction in the San Jose area of Northern California. Assessment of ground deformation by lateral flow is made through the use of a set of geotechnical Information Technologies, including GIS, LiDAR, and FEM analysis. By using a geotechnical database consisting of approximately 600 bore...

This paper suggested a new connection protocol, adding cover-plate between shear links and column, which was used to enhance moment and shear carrying capacity of beam, relax the restriction and assure the sufficiency development of plastic deformation of the link, and dissipate more earthquake energy. Considering the scale ratio of 1:3, the experimental data was achieved by a specimen under cy...

Knowledge on the interaction of active structures is essential to understand mechanics of continental deformation and estimate the earthquake potential in complex tectonic settings. Here we use Sentinel-1A radar imagery to investigate coseismic deformation associated with the 2016 Menyuan (Qinghai) earthquake, which occurred in the vicinity of the left-lateral Haiyuan fault. The ascending and d...

The long-term stress-state of the lithosphere results from a combination of boundary forces, surface loads and tractions frommantle flow. Here, we have employed a numerical technique which allows for the selfconsistent treatment of the interaction between the lithosphere and mantle and takes into account the deformation of the free-surface. We have used this to study lithospheric dynamics in or...
