地壳形变与地下水异常关系研究进展

PROGRESS OF RESEARCH ON RELATION BETWEEN CRUSTAL DEFORMATION AND UNDER-GROUND WATER ANOMALIES

地壳形变异常是地壳构造变动中直接的表现 ,也是物理含义最为明确的地震前兆之一。地下水异常能够提供多种形式的构造活动过程 (包括地震 )。这两类异常能够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 ,并成为地震预报的重要手段 ;而它们之间既相互联系又相互影响。因此 ,对两类异常关系的研究对于识别地震前兆特别是短临前兆至关重要。归类了地震孕育模型及其前兆异常机理 ,并对前兆异常机理进行归纳整理和简述 ,然后从机理和前兆方面综述了地壳形变与地下水异常关系的研究成果。

The anomaly of crustal deformation is not only one of the most direct expression of crustal tectonic movement,but also the most evident seismic precursor in physical meaning;the anomaly of under ground water can provide polytype tectonic active process(as well as earthquake).The two types of anomalies can reflect precursory information in the development process of earthquake in different ways and with different features and become the important methods for seismic prediction.They are connected and influence each other.So,research on the relation of the two types of anomalies for identifying the earthquake precursor especially the short impending precursor is very important.In this paper,first of all,the siesmogenic models and the mechanisms of precursors are calssified.And the later is summed up and recounted briefly.Futhermore,the relation of crustal deformation with the anomaly of under ground water is summarized in the seismic mechanisms and precursor based on the examples of earthquake.
