Continuous GPS array of Iran and its applications to Crustal Deformation Monitoring and Modeling

Iran is one of the most tectonically active zone in Alpine-Himalayan seismic belt where has been shaken by largely destroying historical and instrumental earthquakes(Engdahl et al., 1998; Ambraseys & Melville, 1982). The shortening between Arabian and Eurasian plates in Iran is mainly distributed on Zagros and Alborz belts. Several GPS campaigns were carried out on different networks between 2000 and 2008and provided the horizontal velocity field in Iran. In this work, for the first time we used a continuous GPS network, precise leveling, Insar, and absolute Gravimetery are usedto better understand the tectonic deformation in different active part of the country. These techniques will bring us more precise information on crustal information(shortening and strike-slip rate in Iran as horizontal movements, subsidence and uplift as vertical movements) and geophysical phenomena such as ionosphere disturbances and water vapor.
