摘要
探讨了利用地震矩张量反演断裂形变带运动学参数的方法，将其应用于汾渭断裂带现今运动学特征的研究．结果表明，汾渭断裂带的运动呈Ｎ２２°Ｗ方向拉伸，Ｎ６８°Ｅ方向压缩．其平均拉伸位移速率为０．１５ｍｍ／ａ．
In this paper,the theory and method for inversing the kinematics parameters of a fault zone are discussed,and applying them,the present kinetic characteristics of Fen wei fault zone are studied.The results show that Fen wei fault zone extends in the direction of N22°W and is compressed in the direction of N68°E.The mean extending rate is 0.15 mm/a.
