Abstract: One of the prominent examples of the surface deformations that have been formed without destructiveearthquake failure since last 10-20 years in the west Anatolian extensional province, observed in Bolvadin settlementarea located at the middle part of the Afyon-Akşehir Graben. In this area, some linear surface deformations thatstarts on the southwestern side of the town and can be followed until the northwestern side have been observed sincelast 4 years. During the field studies in Bolvadin area, progressive surface deformations such as surface faults andearth fissures whose length varies between 300 meters and 2 kilometers and strike varies between N15°E and N70°Eare mapped. The northernmost one of the surface deformations mapped in settlement area of Bolvadin have thecharacteristics of the southwestern continuation of Bolvadin Fault. Besides this, qeologic and morphological analysisindicate that the southeastern block is a down-dropped block and vertical displacements along the deformation zoneare varies between 10-40 cm. According to geodesic data, measured rates of vertical offset in the Bolvadin is 7.1 cm/year. In order to find out the effect of active tectonism on formation of surface deformations, further trench basedpalaeosismological studies are necessary.
