| Abstract: | It has been verified by plentiful existing observations that the ionospheric disturbance do appear prior to earthquake.In this paper,on the basis of the ionospheric TEC derived from the GPS observation data from the reference stations of Crustal Movement Observational Network of China,we processed and analyzed the ionospheric TEC data prior to the WENCHUAN Ms8.0 earthquake by Kalman filtering and then we compared the results with the previous conclusion,the results indicate that the establishment of the mod... |
