摘要
根据地震矩张量反演地壳水平形变速度包括两个主要步骤:(1)由震源机制解计算地壳的平均应变率;(2)由应变率求速度场。文中对反演的理论与方法作了详细论述,并讨论了速度场内的相对大地转动和线性结构的整体转动以及速度场的误差椭圆的计算方法
The theory and method of inversing the horizontal velocity field of crustal deformation by seismic moment tensor are described in this paper.The steps of the inversing are as follows:(1)calculating the average strain rate of crustal by focal mechanism solusion and (2) calculating the velocity field by the strain rate. The computative methods of the relative rotation in the velocity field and the whole rotation of linear structure and the error ellipsoid of the velocity field are also discussed.
