The Changle-Zhao’ an fault belt is an important belt bordering the southeast coast of China. It wasformed in pre-Mesozoic time and has undergone polyphase activities of different modes ever since. Through astudy of the data concerning the Cenozoic strata, volcanism. seismicity, hydrothermal activity and crustaldeformation, the characteristics of the neotectonic movement of this fault belt were preliminarily ascertained,the amplitudes and rates of recent faulting in some places were calculated, and the intensities of the activities invarious structural basins along the fault zone were compared. Besides, this paper also discusses the main causefor the origin of the Quanzhou-Shantou strong earthquake tectonic zone.
