Abstract

In this study, distribution of landslides densely seen Karlıova Basin and surrounding is observed in accordance with elevation, slope, aspect and NDVI parts. Karlıova Basin is a tectonic origin depression which has begun to open between right-lateral strike-slip North Anatolian Fault (NAF), and left-lateral strike-slip, Eastern Anatolian Fault (EAF) in Kuvaterner. These faults have an important effect on formation and development of basin. The major effect is that high slopes are seen in intersection of the basin and mountainsides surrounding the basin and Karlıova Basin run parallel to the faults. The seismic-activity rate is very high in around the basin because of the effect of faulting. The lithology in Karlıova Basin and surrounding mostly consists of basaltic and tufa. That lithologic construction leads the basin to be more rainy, the landslides in Karlıova Basin to happen densely and high slope, seismic activity. The landslides are densely seen in Göynük Stream Valley and Kargapazarı Basin around the basin. Apart from these areas, they are densely seen in surrounding the basin due to tectonic and lithological formation. As it used to be in Göynük Stream Valley, the happening of the landslides accelerates along steep slopes where plant cover is weak and volcanites are broken by faults. The landslides directly affecting human activities like accommodation and transportation in Karlıova Basin and the surrounding have a deep effect. However, agriculture, range fields and drinkable water supply network of Bingöl City are affected negatively by the landslides per year. Morphology is constantly changing because of the landslides. Considering the seismic and tectonic formation of that area, the ongoing of these moves is indispensable. To decrease the probable harms of the landslides, it needs to construct the landslide susceptibility maps including the basin and surrounding. This study largely contributes to formation of the landslide susceptibility maps.
