Slip rates and seismic moment deficits on major active faults in mainland China
[1] The Chinese mainland features widespread active faults and intensive seismic activity; both can be described in terms of slip rates on these faults. Previous studies of fault slip rates in mainland China have focused on individual faults or fault segments, and large discrepancies exist among results derived from different methods. Here we derive a self‐consistent estimate of the slip rates ...
متن کاملCurrent slip rates on conjugate strike-slip faults in central Tibet using synthetic aperture radar interferometry
[1] We estimate the current slip rates on active conjugate strike-slip faults in central Tibet using repeat-pass synthetic aperture radar interferometry (InSAR). The conjugate fault systems are centered along the east trending Late Jurassic–Early Cretaceous Bangong-Nujiang suture zone and are composed of NE striking left-slip faults to the north and NW striking right-slip faults to the south. T...
متن کاملStress-Breakdown Time and Slip-Weakening Distance Inferred from Slip-Velocity Functions on Earthquake Faults
We estimate the critical slip-weakening distance on earthquake faults by using a new approach, which is independent of the estimate of fracture energy or radiated seismic energy. The approach is to find a physically based relation between the breakdown time of shear stress Tb, the time of peak slip-velocity Tpv, and the slip-weakening distance Dc, from the time histories of shear stress, slip, ...
متن کاملMaerten: Slip Vectors on Intersecting Normal Faults
Numerical models based on linear elasticity theory predict asymmetric slip distribution with a steep slip gradient near the line of intersection of intersecting normal faults. They also predict a discrepancy between the direction of slip on the fault plane and the direction of resolved shear stress. Both variations in slip magnitude and direction are due to mechanical interaction between the fa...
متن کاملDetermination of long-term slip rates of faults in the eastern part of Iran plateau using finite element kinematic model
Since Iran plateau is located in the Alpine-Himalayan Orogenic belt, it is recognized as a region with a high seismic risk. Thus, investigation of geodynamic activities of the faults, their slip rates and corresponding deformation fields is very important for quantification of possible seismic risk in this region. The aim of this study is to analyze the tectonic features of eastern part of Iran...
