Original Paper


A long, surface breaking, strike slip fault inclined to the vertical is taken to be situated in a linearly viscoelastic half space of Maxwell type representing the lithosphere–asthenosphere system. Tectonic forces due to mantle convection and other related phenomena are supposed to be acting on the system. Under the action of these forces stresses accumulate in the region and fault undergoes a creeping movement when the accumulated stress exceeds the frictional and cohesive forces across the fault. In this paper the creep velocity is supposed to be decelerating in nature. A numerical technique based on finite difference scheme with discontinuity has been developed to solve the related boundary value problem numerically. The resulting scheme is solved with the help of suitable MATLAB code and the nature of stress, strain in the region is shown graphically.
