利用 ＮＵＶＥＬ－１全球板块模型的 １１２２个数据、菲律宾海板块（ＰＨ）的地震滑动 矢量以及由ＧＰＳ测得的的运动速率，根据全球板块模型反演了包括菲律宾海板块在内 的１２个板块相对于太平洋板块（ＰＡ）的欧拉矢量．推得了菲律宾海板块相对周围其他板 块的运动矢量．这一结果与观测值相当符合，并能满足开罗林板块（ＣＲ）附近的ＣＲ－ＰＨ， ＰＡ－ＣＲ边界上的地质及其他地球物理约束．最后利用板块运动参数讨论了菲律宾海板 块的形变．  相似文献   

Determination of Euler parameters of Philippine Sea plate and the inferences

Euler vectors of 12 plates, including Philippine Sea plate (PH), relative to a randomly fixed Pacific plate(PA) were determined by inverting the 1122 data from NUVEL-1 global plate motion model, earthquake slip vectors along Philippine Sea plate boundary, and GPS observed velocities. Euler vectors of Philippine Sea plate relative to adjacent plates are also gained. Our results are well consistent with observed data and can satisfy the geological and geophysical constraints along the Caroline(CR)-PH and PA-CR boundaries. Deformation of Philippine Sea plate is also discussed by using the plate motion Euler parameters.  相似文献
