The surface expression of the North Anatolian Fault between the Sea of Marmara and the Gulf of Saros, Turkey was determined using Landsat 5 Thematic Mapper (TM) and Systeme Probatoire de l'Observation de la Terre (SPOT) high resolution visible (HRV) Panchromatic images and a digital elevation model (DEM) based on 1 : 25 000 scale topographic maps. The remotely sensed data had been enhanced to reveal linear details. Between Gazikoy ( Marmara Shore) and Saros two small releasing steps were identified, one to the east of Murseli village and the other between Murseli and Yayakoy villages. Hitherto, a single straight fault line had been drawn between Gazikoy and Saros on the geological map of this region. Between the Yenikoy and Sofular villages, the fault strike bends similar to7degrees further to the SE. The course of the fault between the Sea of Marmara and the Gulf of Saros is, therefore, more complicated than formerly believed and this is probably because the fault has utilized the preexisting structures of the Neo-Tethyan subduction - accretion complex.
