山西裂谷带形变应变场演化特征及与地震的关系

Research on Relationship Between Evolution Characteristics of Crustal Deformation,Strain Field and Earthquakes along Shanxi Rift Zone

利用山西及邻近地区的地壳形变测量资料,给出山西裂谷带形变场(垂直、水平)演化图像、重力场演化等信息;研究山西裂谷带拉张、挤压、地面沉降等受力状况与地震活动之间的关系,结合多次中强地震震例,探讨地震预报的方法。

This paper systematically studies the measurement data of crustal deformation in Shanxi and adjacent regions, gives the evolution images （vertical, horizontal） of the deformation field along the Shanxi rift zone, and the evolution of gravity field, etc. The paper also studies the relationship in the Shanxi rift zone between seismic activity and stress state, including tension, extrusion and ground subsidence, etc. Further, based on several moderately strong earthquake incidents, the paper discus- ses methods of earthquake prediction.
