Strain analysis along the North Analtolian Fault by using geodetic surveys

In earthquake prediction studies geodetic surveys play a very significant role. For this purpose, in Turkey, three micro geodetic networks have been established across the North Anatolian Fault. Of these, the Ismetpa§a Network is the subject of this paper. From the observations in combined triangulation—trilateration mode in 1972 and 1982 the horizontal movements and strain components were determined. Afterwards the parameters of the best fitting deformation model were computed and analyzed. The results show that the Anatolian plate has about a 1 cm/year westward motion, and there exists considerable strain accumulation in the area.
