SummaryMany civilizations were developed in the place where The Western Anatolia affected by a lot of destructive earthquakes throughout history. The existence of about 13 earthquakes occurred at the historical period in the zone encompassing the study area are known. The vast majority of these historical earthquakes are concentrated around the Gediz graben. When the historical earthquake activity of Gediz Grabe is analyzed, the existence of earthquakes whose magnitude is bigger than VII is known in the western area of the graben in B.C. 17, 1592, 1850, 1862 years, and in Denizli region at the intersection of the Great Menderes Graben, at the eastern area of the Graben in A.D. 60, 494 years. Later than the specified dates, 1969 Alaşehir earthquake is known to occur in the eastern area of the graben. According to the study done by Ayhan and the others in 1989, the outside of central and western parts of Gediz graben is not active. Seismic activity between Sarigol-Buldan forming the southeastern end of the Gediz graben increased again especially around Buldan in the first 3 months of 1997. The seismic activity among Alaşehir-Sarıgöl-Buldan is not only concentrate the central and edges of the graben, but also is observed quite a lot of particularly between Sarigol-Buldan at areas exposed in aged units characterized mainly pre-neogene (Barka et al., 1998). The consistent of E-SE part of the graben with high seismic activity reveal to have the seismic potential more of this part of the graben (Eravcı, 2007). Movements along the Sarigol fault are displacements which are controlled by fault slope and convex surface of sliding. Deformations developing on different blocks along the fault zone in order to document of this situation must be monitored by tools can make precise measurements. We will investigate interseismic strain accumulation using InSAR data from TerraSAR-X image for in western parts of Gediz graben . We will use the Persistent Scatterer Interferometry (PSI) and Small Baseline Interferometry (SB) methods with TerraSAR-X data. Using time series analysis we aimed to map areas of tectonics movements.
