Abstract
Crustal movement studies are very important tool in understanding the geodynamic of the Earth on regional and local scales. The Gulf of Suez area is one of the most seismo-active regions in Egypt. It has been selected for this study because of its economic and strategic importance. In this study, GPS observations will be used to investigate the recent crustal movements and its relation to seismicity and tectonics along the Gulf of Suez and surrounding area. More light will be shaded concerning the opening of the northern part of the Gulf of Suez. A geodetic network consists of 12 GPS stations was established and observed five times in different campaigns. The observed data was analyzed using Bernese 5.0 software and the velocity vectors along the Gulf of Suez were determined. The estimated annual horizontal velocity of the Gulf of Suez region including the annual horizontal velocity of the African plate using model NUVEL 1A are found to be in the range of 29 to 31 mm/yr with an uncertainty level of 3.5 mm/yr. The obtained results showed that the Gulf of Suez is an opening region in northeast direction and deforming one in the southern part. The results show also that this region can be divided into three main provinces. The seismic data analyses support our obtained results through the analysis of earthquakes focal mechanism.
