Étude des déformations saisonnières observées par GPS appliquée à l’île de la Réunion et au bassin Amazonien

Abstract : The Earth crust is the subject of many deformations which are caused for instance by no tidal loading. The three types of no tidal loading are atmospheric, hydrologic and no tidal oceanic loadings. Scientists have established models for these loadings, nevertheless the phenomena which are responsible of the loading are hard to describe. The aim of this study is the validation of these models and the additive model which created the final model from the two special areas of study : the Amazonian basin and Reunion. The Amazonian basin is interesting due to the large hydrologic variations in this area. The analysis of Reunion must validate two INSAR pictures used in another study. This study requires the creation of time series with iPPP (integer Precise Point Positionning) method and loading models supplied by van Dam and Li (University of Luxembourg). Statistics of these data, spectral separation and analysis by SSA (Singular Spectrum Analysis) are three complementary ways to isolate loading phenomena.
