用地震矩张量反演的鄂尔多斯地块运动与临汾大地震

Using Inversion of Seismic Moment Tensor for the Movement of Erdos Block and the Linfen Macroquake

本文用地震矩张量反演断裂形变带运动学特征的方法，讨论了近６００多年来鄂尔多斯地块不同时段的构造运动。结果表明，大华北第３地震活动期中该地块运动增强，其构造运动参数２倍于正常期，指出１６９５年临汾大地震是在此区域构造运动背景下产生的。

Using the method of that the seismic moment tensor inverses the kinetic Character of the fracture defor-mation belt,the paper discusses the tectonic movement of Erdos block in different time range since recent 600vears. The result shows that the movement of the block enhanced in the third active period of North China,the parameters of its tectonic movement were 2 times the value of the normal period,the Linfen macroquakeoccurred in the tectonic movement background of the region.
