Özet

The study was able to describe the ancient landslide debris around Guzelyali Village. Also, the remains of horrendous ancient landslides have been discovered in northeast of Erenkoy Village in Canakkale. In this frame, aim of the study is to determine the preparatory and triggering factors that form the landslides by analyzing the occurrence and development mechanisms of these landslides with the geological and geomorphologic methods. The evidence for the ancient landslide triggered by 1875 Erenkoy-Canakkale Earthquake presented in this paper, which is located near Erenkoy. Ancient landslide complex around Erenkoy-Guzelyali area has the distinction of having one of the largest, landslides in Canakkale. The total area of the ancient landslides is approximately 3.75 square kilometers in size. Historical landslides near Erenkoy have been noticed by land features bearing two hallmark characteristics. These are: a jumbled assortment of rocks at the base of a slope, and a cuplike or sharp-straight topography cut out of the hills where the slide might have come from. Post 1875 erosion activity have partially erased much of the evidence of landslide. It was assumed that landslide deposits near Guzelyali Village were produced by multiple landslide events. Probably some of the slides, originated by earthquakes consisting of many events, likely several -undred years between them. Mentioned landslide debris was recently moved again as creep-type landslides. Ancient landslide debris offers danger signs for northeastern Guzelyali housing developments. Ancient Guzelyali's landslide debris and related landslide is older than Erenkoy's landslide.
