Abstract

To know how coordinates of points on Earth surface are changing by time is very important for geodetic applications. At first step, the paper presents a time dependent model for point displacements caused by plate tectonics in ALBORZ Mountains, then displacements for points of ALBORZ classical geodetic network will be estimated. This estimation is performed for points without continuous GPS observations. Velocity vectors of an independent research based on GPS observations between 2000-2008 are used as constraints of this model. Modeling is based on analytical relations of OKADA. In this research, using a method of inverse genetic algorithm, dislocations and depth fault are computed. Minimum ROOT MEAN SQUARE ERRORs of the model for interseismic displacements is about 0.97 mm/yr. The total displacement of each station is obtained by summation of the vector of the modeled interseismic movement and displacement vector fields for earthquakes with magnitude which are computed directly by OKADA relations. Maximum amount of changes of the coordinate stations of the 25 year old classical geodetic network in ITRF frame approximately is 80 cms which cannot be neglected.
