Abstract
Seismically active regions are associated with fault systems and the movement of these faults influences the nature of stress accumulation/release in that region. For an in-depth analysis of the effect of such movement, we here developed a mathematical model by considering a surface breaking, inclined, finite strike-slip fault in the visco-elastic medium of Burger’s rheology. The caused deformation in the medium was then considered. Analytical expressions for displacements, stresses and strains were derived using Green’s function technique and Laplace transform. The variation of displacements, stresses and strains due to the locked fault was studied. These variations are graphically depicted for different inclinations of the fault with the free surface and for different fault movement velocities using MATLAB. Such studies may shed some light on the nature of stress and strain accumulation/release due to fault movement in Burger medium.
