Outline
In order to more clearly depict the fault distribution in the seismic profile of urban active fault detection, seismic attributes are extracted from the seismic data of urban active fault detection based on the theory and implement methods of variance body, coherence body, instantaneous phase and wave impedance inversion, and comprehensively analyze the application effects of various attributes, and use the attribute fusion method to superimpose display the seismic attributes. The results show that using seismic attribute analysis and attribute fusion can reduce the difficulty of fault identification, improve the accuracy of fault identification, and the fault distribution is more regular.
