Deformation of a two-phase medium due to a long buried strike-slip fault

Abstract

The aim of the present paper is to obtain the twodimensional deformation of a two-phase elastic medium consisting of half-spaces of different rigidities in welded contact due to a buried long strike-slip fault. The solution is valid for arbitrary values of the fault-depth and the dip angle. The effect of fault-depth on the displacement and stress fields for different values of dip angle has been studied numerically. It is found that the displacement field varies significantly for a buried fault from the corresponding displacement field for an interface-breaking fault. The contour maps showing the stress field for various dip angles for buried and interface-breaking fault have been plotted. It has been observed that the stress field varies significantly for a buried fault from the corresponding stress field for an interfacebreaking fault.
