Abstract

The Eastern Mediterranean deformation is relevant to the deep tectonics but it is complicated. It is related to the collision between the passive margins of a major plate (Africa), locally acting as a continental indenter against the active margin of another plate (Europe). The Bouguer anomalies in the study area (Eastern Mediterranean region) are various between −40m Gals at the southern margin of Turkey to 210 mGals (Herodotus Abyssal Plain).

The thickness of the crust varies approximately between 8 and 38 km. Thinner crustal thickness of about 8–14 km are found in the oceanic domains, namely, Herodotus Abyssal Plain.

The highest seismic strain rate release, S−1, of order, 10−14, is observed in Hellenic Arc. The lower strain rate release of, 10−25, is observed in front of the Egyptian Coast (African Plate). The seismic strain release around Hellenic Arc, 10−14, is relatively higher than the Cyprean Arc, 10−17.
