Geodetic methods make major contributions to geodynamic studies. Microgeodetic networks which are designed for detecting crustal movements in seismically active areas are capable of monitoring 3D position changes with a few mm. The study of monitoring horizontal crustal movements on the western part of NAFZ has started by Geodesy Department of Kandilli Observatory and Earthquake Research Institute (KOERI) of Bogazici University in 1990. Three geodetic control networks were established in Iznik, Sapanca, and Akyazi regions in order to monitor crustal displacements. There are also several on-going and also completed projects which are being conducted by scientists from the universities and the other research institutes for the region of interest.

Since the year 1994, the department has been carrying out their activities in different parts of Turkey (such as western and eastern Turkey) by using GPS technique through the research projects supported by the Bogazici University Scientific Research Projects Fund and Scientific and Technological Research Council of Turkey (TUBITAK).
