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 QUADRATICALLY 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.
