我国断层形变观测在地震研究中的进展及问题

Progress and Problems of the Fault Deformation Observation in the Earthquake Researches in China

已获得的主要成果有 :区域断层活动特点 ,断层活动性与强震发生的关系 ,应用断层形变确定活动块体的边界 ,依据断层形变提出地震危险性的估计 ,断层活动监测方案的完善等。目前存在的主要问题是观测规模萎缩 ,观测方法落后 ,研究工作滞后。

The main achievements in the fault deformation observations are as follows: the characteristics of regional fault activity; the relationship between fault activity and strong earthquake occurrence; the determination of the boundary of active land block by use of fault deformation; the estimation of seismic risk according to fault deformation; perfection of fault activity monitoring plan, etc. The main existing problems are the reduction of observation scale, the lag of observation method and research work.
