Propagation of SH Waves in a Double Non-Homogeneous Crustal Layers of Finite Depth Lying Over an Homogeneous Half-Space

Abstract

The present paper studies the Propagation of SH waves in a double non-homogeneous crustal layers lying over an isotropic homogeneous half-space, where upper layer ((i.e. rigidity and density varying trigonometrically with depth) and intermediate layer (i.e. rigidity and density varying parabolically with depth). The wave velocity equation has been obtained. Closed form solutions have been derived separately for the displacements in two non-homogeneous crustal layers and lower half-space. The dispersion curves are depicted by means of graphs for different values of non-homogeneity parameters and thickness ratio for layers.

A comparative analysis (real-time data and theoretical results) for propagation of SH waves in a viscoelastic model influenced by a point source

“…The basic theoretical and algorithmic aspects of memory-efficient implementation in realistic attenuation of seismic wave propagation with material discontinuities is discussed by Kristek and Moczo [6]. Sethi et al [7] studied the propagation of SH waves in a double crustal layer of finite depth lying over a homogeneous half space. Chatterjee et al [8] analyzed the shear waves in a viscoelastic heterogeneous layer lying over an initially stressed half space.…”
