The investigations on crustal deformation in China under ITRF97 plate model using data of Crustal Movement Observation Network in China

After setting up the global plate motion models based on the International Terrestrial Reference Frame ITRF97, we establish the latest sub plate models in China using velocity fields of 79 GPS base network on the basis Crustal Movement Observation Network of China. In comparision with NNR-NUVEL1A geological model, our model presents the present-time crustal deformation at the span of years. As the background velocity field, the Eurasia model based on the ITRF97 velocity fields is recommended to investigate present time tectonic deformation in China rather than NNR-NUVEL1A.
