Abstract:in order to study development characteristics of Cenozoic faults in Dongpu depression, through explanation of seismic profiles in different sections, according to activity rates of fault activities, activity characteristics and strength of Dongpu depression in Cenozoic faults have been analyzed, and the characteristics and intension of the faults in different regions have been compared and analyzed in Dongpu depression. As showed by the results, development characteristics of faults in different regions have some similarities and differences. The faults evolution is influenced by both the Eurasian tectonic system and the Pacific tectonic system. Meanwhile, the influence is different in different regions.
