Q Value Tomography in Laterally Inhomogeneous Media: Method, Software and its Application

Q value structure of the crust has great significance for understanding of non-elastic nature of crustal structure,thermal activity,crustal inhomogeneity,and fault distribution.Based on absorption characteristic time t^{* the GUI software for two-dimensional Q tomography has been written in this paper.Amplitude spectra of deep seismic sounding data can be calculated quickly and easily.The absorption characteristic time reflecting seismic wave attenuation can be obtained through fitting the amplitude spectra,and two-dimensional Q structure can be obtained by two-dimensional Q tomography using t* data.The real example shows that the method and the software are effective and feasible.}
