Popis:	It is becoming popular to extract fracture information from wide-azimuth P-P reflection seismic data. The extracted crack density is not influenced by the phase of the seismic data. The extracted fracture orientation is sensitive to the phase of seismic data and the nature of the rocks. Other information besides the amplitude and NMO velocity of seismic data is needed in order to uniquely determine the fracture orientation. This paper discusses the ambiguity of the fracture orientation and how it can be resolved. Todorovic-Marinic et al (2004) discussed the stabilization of crack density.
