INVERSION OF THE PRESENT KINEMATICS CHARACTERISTICS OF FEN WEI FAULT ZONE FROM SEISMIC MOMENT TENSOR

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.

Abstract:

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.
