Applications of GPS to Current Crust Movements and Monitoring Seismic Precursors

摘要: 以"中国地壳运动观测网络"科学工程项目产出的GPS观测资料为基础,采用球坐标系下非连续变形算法对资料进一步做了形变计算,以此为基础,对我国大陆地块及其边界带运动与形变进行了分析。对GPS基准站的连续观测序列采用小波变换进行分解变换,分析了部分震例,探讨了GPS连续观测序列提取地震前兆的方法。

Abstract: In accordance with GPS dada produced from "Crust Movement Observation Network of China",the current motin and deformation of the blocks and their boundaries in the continent of China are computed and analyzed,using "inverse DDA of a block system in the sphere coordinate".And making wavelet transformation for the observational sequences of GPS continuously tracing stations,we investigated approaches abstracting precursory information from the continuously observational sequences of GPS with analysis of earthquake events occurred.
