摘要 采用GAMIT和GLOBK软件在ITRF框架下解算得到IGS连续观测站时间序列[1],针对汶川震区附近的IGS观测站时间序列进行分析。应用经验模态分解方法对IGS连续观测站时间序列进行全面分析,揭示汶川震区附近IGS连续观测站时间序列异常和趋势变化与汶川地震震后形变的关系。 We adopt GAMIT and GLOBK software to get IGS observation stations＇ time series through global adjustment in IRTF, and we analysis the IGS observation stations time series near Wenchuan earthquake zone. We applied EMD to the time series of IGS stations near Wenchuan earthquake zone for a comprehensive analysis to reveal the relation between the ab- normal time series and seismie deformation after WenChuan earthquake.
