Interactive software for three-dimensional Q tomography and its application to seismic data processing

Abstract

Abstract:

Q-value structure of the crust is of great significance for understanding of non-elastic nature of crustal structure, thermal activity, crustal inhomogeneity, and fault distribution. We present an interactive software for three-dimensional Q tomography based on absorption characteristic time t^*. Amplitude spectra of seismic data (P-wave and S-wave) can then be calculated quickly and easily, absorption characteristic times can be obtained through fitting amplitude spectra, and three-dimensional Q structure can be obtained by using the Q tomography method and t^* data. The real example shows that the method and software are effective and feasible.

Key words: three-dimensional Q tomography, absorption characteristic time, Q value structure, seismic waveform, interactive software
