| Abstract: | A method for computing crustal horizontal velocities and strain-rates using repeated GPS survey and other crustal deformation measurement was presented in detail. Based on the data taken from the Crustal Deformation Monitoring-Networks with GPS in the whole country and North China, we derived the average horizontal velocities of the points of the networks and simulated the horizontal velocity and strain-rate fields in the corresponding areas. From these results, we can conclude: (1) GPS can effectively detect current crustal motion and deformation, and (2) the method presented in the paper is valid, and through its use, calculated results can provide more information about current crustal motion and deformation than direct observation data. |
