| Abstract: | By means of the synthetic model for rigid movement and strain of the intro-plate blocks,and through computing the accumulated difference displacements derived from the observation fiducial GPS stations in the northeastern edge of Qinghai-Tibet block,the dynamic variations of the continuous deformation parameters in this area are obtained.The results show that there was coherent vary tendency between these parameters before and after the KunLun Mountains Ms 8.1 earthquake,it is discovered that the four time series,the east-westward strain,the least principal strain,the superficial expansion rate and the second shear strain are significant.The mechanism of strain releasing and adjustment induced by the earthquake in the area can be interprated with this Model.It is possible to identity imminent anomalies of a large earthquakes in the region by assembling deformation parameters. |
