Abstract     

In this study work the idea of the optimal design of GPS monitoring network is extended in order to estimate the parameters of a single strike slip fault: i.e. slip rate and locking depth. By using some numerical examples, the influence of the GPS station distances from the fault trace has been investigated. The results show that far GPS stations have more advantages for estimating of slip rate. In contrast, the near stations are important for locking depth.
