Abstract

Simultaneous iterative reconstruction technique (SIRT) is used to estimate properties of seismic wave attenuation in earth. The data used in this study is the acceleration values of S wave. The acceleration amplitudes are converted to displacement amplitude in frequency domain. The value of Q obtained is found to be increasing with depth and shows strong directional dependence with Q values increasing in north direction. The Q values are varying between 300–900.In this paper we describe the application of SIRT method to estimate attenuation.
