Abstract
Numerical stimulation was utilized to study the seismic wave attenuation in random medium. The main reasons of attenuation in elastic media were the spherical divergence and scattering wave caused by in homogeneities with variant scales. The elastic wave attenuation in random media cannot be analyzed by analytic method, so the numerical stimulation was the only way to discuss the problem. Rotated staggered finite difference method was chose to stimulate the situation. 6 random media were constructed with different correlation length. Numerical Stimulation was implemented in them, and particle displacements in certain locations were record. These records were compared with the ones in the corresponding homogeneous media to discuss the attenuation.
