The scattering and attenuation of high-frequency seismic waves are considered important characteristics to be quantified to physically characterize the Earth medium. This chapter presents the measurements of attenuation of seismic waves and discusses physical mechanisms of attenuation in the lithosphere, including intrinsic absorption and scattering loss because of distributed heterogeneities. As a model of attenuation, it introduces an approach for calculating the amount of scattering loss in… CONTINUE READING

For the single layer Gaussian medium model, the model parameters are the RMS velocity perturbation ε, correlation length a and the layer thickness H

Uniform random medium model for the lithosphere
  • Correlation length a can be estimated from a measurement of the transverse correlation of log amplitude and phase. The layer thickness H and the wave speed perturbation ε can be obtained from the measured variance and covariance of v and φ. This single layer isotropic Gaussian medium model has bee
