| Abstract: | In this paper, the South China coastal area is divided into several fault block areas (first class), sub-areas (second class) and mini-areas (third class) based on their dynamic signs, heridity, uniformity, paricu-larity and the mode of action of tectonic stress. Their tectonic geomorphological features are elaborated and the amplitude as well as the rate of relative motion since the end of the late Pleistocene epoch are estimated from 14C data of the samples which fundamentally represent the sea level in different periods. It is found that the value of amplitude and rate of fault block movement, tend to become smaller from the east and west towards the middle. This feature could be related to the "screen" effect of the Taiwan -Penghu-Quanzhou-Shantou strong earthquake area and the Leizhou-Qiongya earthquake area. |
