Abstract

In this research, the role of various existing tectonic plate and faulting motions in the middle-east region has been investigated on the geodetic data and its purpose is to estimate the contribution of these motions in the GPS velocity field of campaign global geodynamic network in the region of Iran using fracture mechanics concepts and dislocation modeling. For modeling the faulting data in the Middle-East region were decomposed to various categories by considering the tectonics of the region and were included in the model and the induced velocity field due to them were modeled and compared with GPS velocity field. Obtained results show that the contribution of Arabian plate in observational GPS velocity field is more than the contribution of Anatolian plateau faultings and inside faultings of Iran create an internal north-south compression component and a counterclockwise rotation component in the modeled velocity field. According to modeling results about 30% of GPS velocity field components are produced by Iranian inside faults, 60% by Arabian plate and 10% by Anatolian plate.
