Effects of Heterogeneities on the Propagation, Scattering and Attenuation of Seismic Waves and the Characterization of Seismic Source.

Abstract

This study has examined the attenuation of local/regional S codas from 0.25 Hz to Hz in the Hindu Kush region. A goal study was to separate the relative contribution of scattering versus intrinsic anelasticity to the attenuation of coda waves. Coda attenuation has been analyzed in the frequency domain using a radiative transfer equation technique, which includes multiple scattering, and in the time domain using weak and strong scattering approximations.
