Eastern Mediterranean gravity anomalies, supplemented by Anatolian anomalies and linear correlation coefficient analysis of gravity values and topographic elevation along several profiles in Anatolia are evaluated. It is observed that the hundred milligals difference in gravity values, the gravity anomaly-topography relations and peculiar isostatic conditions are seen in Eastern Mediterranean are also seen over Anatolia. It is observed that, while The Eastern Mediterranean is over-compensated with respect to gravity anomalies, Anatolia is under-compensated. In the light of peculiar isostatic conditions and gravity value-topographic relations, it is suggested that the compensation conditions in the region are due to a low-velocity asthenosphere in the mantle. Local positive isostatic anomalies of Cyprus and Aegean sea are explained by local, near surface heavy material over the low-velocity asthenosphere.
