Abstract: In the present paper, a comprehensive study of dispersion characteristics of SH-waves in a monoclinic crustal layer lying over a dry-sandy half-space, with special emphasis on the effect of a triangular irregularity at the interface, has been conducted.We have considered both isotropic and monoclinic layer for the analysis of SH-wave propagation with or without sandiness in the half-space.The governing equations representing equation of motion of SH-waves in a monoclinic medium, is formulated to develop dispersion relation.Further, the results are analyzed and discussed for the variation in various physical parameters such as depth of triangular irregularity, sandiness and the directional dependencies in the monoclinic medium.Moreover, a comparative study has been conducted to assess the extent to which these parameters affect SH-wave propagation differently in monoclinic and isotropic layers.These results are illustrated graphically to highlight the importance of considering interfacial irregularity in seismic wave studies.
