Abstract The results of multiphase relevelling data obtained from 1956 to 1999 suggest that the current tectonic activities of the Jiaodong, Subei, TaishanYishanMengshan and Huaihe blocks are characterized by tilting and some of them predominate in depression state in certain periods. Among the 4 blocks, the Jiaodong block was distinctively active in the period of 1956-1978, which was related to the development and occurrence of Bohai Ms7.4 earthquake in the northword extending segment of the Tanlu fault zone. The Subei block was rather active in the periods of 1978-1985 and 1990-1995, which was associated with the development and occurrence of the Ms6.2 and Ms6.1 South Huanghai earthquakes in the eastern part of the Subei block.
Key words :
