Analysis and interpretation of the eastern Mediterranean geophysical data

Neotectonics of the Eastern Mediterranean is still active and the motion of the African Plate, Arabian Plate and the Eurasian Plate controls it. The westward motion of the North Anatolian Fault Zone and southwestward rotation of the Aegean region shape this region. Therefore, to create the subduction model of the Cretan Arc, Seismological data (USGS) and gravity data (from 1971-74 Shakleton Cruise) of the region, which is defined by the 23-28 longitudes and 33-38 latitudes, were collected.Thickness of crust values were found relatively low along the volcanic arc same as Von Frese (1982). Especially, changing of the system around the Pliny, Strabo trenches (strike slip fault system) affect the structural conditions. Because of the undulated bathymetric values can be related the relative thickness differences in the southeast region of the Crete and these strike slip fault system to reach over to Turkey with Fethiye Burdur fault system. Therefore analyzing of this system is very important to solve tectonic problems in global focusing in coastal civilization in future.Finally, bathymetric and tectonic knowledge were combined and then Bouguer Gravity Anomaly Model were created with winlink software According to this geometry of subduction zone crustal thickness variations and moho depth were defined and characteristics of the region were described with seismological and gravity data.
