Abstract

Many earthquakes with moderate magnitude have occurred in many areas in the world. The common procedures to extract the dynamic responses mainly depend on monitoring the change of the points in a time interval. This method could not be used to fully extract all dynamic parameters accompanied by the earthquake, to overcome these defects, and to analyze the seismic wave of those earthquakes, using the precise satellite orbit and clock in the technology of PPP GNSS, which became an effective tool for getting the values of the displacement of the point more accurate up to millimeters. In this paper, we apply the PPP-GNSS technique to evaluate the station's displacement components and the station's heights also in three different periods from the earthquake, based on the Bernese GNSS 5.2 software to get the estimated station coordinates, and CSRS-PPP(natural resource Canada). And determine which method is better and more accurate to be an earthquake prediction to help us now and in the future.
