地壳形变与地下水动态异常特征研究进展

The Progress of Research on Anomalous Characteristics of Crustal Deformation and Under-ground Water Behavior

摘要:

地壳变形与地下流体之间既相互联系又相互影响.地壳形变异常是地壳构造活动最直接的表现,是物理含义最为明确的地震前兆之一;地下流体异常能够提供多种型式的构造活动过程(包括地震)的前兆信息.两类异常以不同的方式和特点反映出地震孕育过程中伴随的前兆信息,从而成为地震预报的重要手段.本文综述了有关地壳形变与地下水动态异常特征方面的研究成果,从机理和前兆特征方面归纳了两种异常的相互关系.

Abstract:

The mutual relation and influence between the crustal deformation and the subsurface fluid are present obviously. The abnormality of crustal deformation is the most direct reflection of crustal tectonic change, and also is one of the most definite seismic precursor on physical meaning,and the anomaly of subsurface fluid can provide polytype precursory information on tectonic active process （as well as earthquake）. This two types of anomaly can reflect precursory information in the development process of earthquake by different ways and features, thereforce become the important methods of seismologic prediction. In this paper, the research achievements of anomalous characteristics is summarised, the interrelation of two types of anomaly is concluded from their mechanism and precursory anomalous characteristics.
