Abstract
Fault movement across a fault is preceded by accumulation of stress near it over a considerable period of time. When this stress exceeds the total cohesive and frictional forces across the fault, a movement which may be sudden or creeping, across it set in. In this study, a creeping movement across a very long, buried, strike-slip fault inclined to the free surface and of finite width is considered in an isotropic, homogeneous, visco-elastic medium of Burger’s rheology type. A mathematical model for such fault movement is developed during the period when there is no fault movement and also for the aseismic period which is restored after the sudden movement. The analytical expressions of displacement, stresses and strains for both the period are determined by the use of Green’s function technique and correspondence principle. Finally, these displacement, stresses and strains are numerically computed with suitable values of the model parameters and the results thus obtained are presented graphically. Such theoretical models may be used for obtaining greater insight into the earthquake processes in seismically active regions.
