摘　　要：本文总结了1990年天祝—景泰6.2级地震前地壳形变异常特征,发现这次地震并未发生在地壳垂直运动最强烈的地方,而是在其边缘。至于断层形变,则随测点与震中关系的不同表现出不同的特征。This paper summarized the anomalous characteristics of the crustal deformation before the 1990 Tianzhu-Jingtai earthquake with Ms 6.2 and found that the epicentre was not located at the site,where the vertical crustal movement was the violentest,but at its verge. As for the fault deformation,it expressed different features with the different relation between the station and the epicenter.
