Abstract

One of the methods for determining the seismic pattern in space and time is to study the occurrence of strain by registering changes in the Earth's Crust constantly using geodetic monitoring networks and satellite and spatial observations. In this paper the method of analysis of movement in geodetic networks by GPS method is described in detail, and, while highlighting the important points in GPS satellite observation planning, the accuracy necessary for these issues, the advantages of using this method and finally the method of strain analysis and obtaining the maximum shear and dilatation parameters in order to interpret the displacement in these networks by finite difference and finite element methods are described in detail.
