The cusp model of catastrophe theory and its expression are mentioned in this paper. The seismic signal is transformed into the normal form of cusp catastrophe. The parameters of catastrophe, such as catastrophic potential, catastrophic time and so on, are calculated in time domain. It is found that the position of abnormality of the catastrophic parameter curve or profile is related to the location of fault. Thus catastrophe theory is potential to detect fault in this paper. The feasibility is analyzed in theory and a practical section is interpreted with improved result. So that the fault detection using catastrophic parameters is feasible and catastrophe theory will provides a potential method for seismic structure interpretation.
