【摘要】 通过对河西地区重力复测资料进行系统分析 ,从动态的观点研究了 2 0 0 0年 6月 6日景泰 5 9级地震孕育发生过程中的重力场演化特征。重力场动态图像较清晰地反映了本区重力场的准均匀态→地震孕育的非均匀态→发震的演化过程 ,还分析研究了特征重力变化与强震活动的关系。更多还原

【Abstract】 The repeatedly measured date of gravity in Hexi area are analyzed; the evolution characteristics of gravity field in the seismogenic process of the Jingtai,Gansu Province earthquake on June 6,2000 are studied from the viewpoint dynamics.the dynamic pattrrns of gravity field mirror clearly the evolution process of gravity field:quasi-homogeneous state→non- homogeneous state→earthquake occurence.Characteristic gravity variation and its relation to seismicity are analyzed更多还原
