| Abstract: | Based on the data of 18 times of leveling carried out during 1954 to 1985, the relative stability degrees of relevelling nodes in the Tangshan area are calculated. According to these results, the characteristics of crustal vertical deformation before and after the Tangshan Earthquake(28/7/1976,Ms =7.8) are studied. Our study indicates that probably since 1968 significant relative movements between structural blocks in that area had appeared and continued till 1978. The seismic fault was in locked state before the quake. Finally, some viewpoints about the deformation monitoring and the evaluation of risk region of a strong earthquake are also presented in this paper. |
