Abstract :Finite element method has been used in this study to know the fault development in the Red Sea rift system. Two models with fault zone and without fault zone are calculated to determine the effect of detachment fault on the distribution of deformation in the Red Sea area under plane strain condition with linear elastic rheology. Influence of layer properties on fault development are compared with two models. Three types of displacement boundary condition (extensional, spreading, and spreading with upward) are also used to examine results and to search the. best fitted boundary conditions. Results of this study show that (1) detachment fault controls the normal fault system in the Red Sea area, (2) friction angle and cohesion are important parameters, and sensitive to fault development, (3) spreading and spreading with upward displacement boundary conditions show the reasonable results which support the active rifting hypothesis in the development of the Red Sea rift system.
