- Abstract:
-
In this paper,the composition and the corresponding analysis methods of seasonal vertical crustal motions obtained by continuous GPS observations are introduced.Then,we discuss on the application of seasonal crustal motions on the verification of vertical motions in campaign GPS observations,monitoring the variation of mass loading,analysis of stress perturbation and seasonal variation of seismic activity,and inversion of crustal structure,etc.At last,we proposed that the application of GPS in the study of seasonal crustal movement is developing towards the integration of multi-means and multi-disciplines. In the future,it is necessary to further improve the data processing model(strategy)and weaken the errors in the results. At the same time,the mechanism of seasonal crustal movement in different regions deserves more in-depth analysis.
