Summary/Abstract: The Black Sea coast is one of the regions of Bulgaria with distribution of a significant part of the Bulgarian landslides. The analysis of the factors influencing the stability of the coastal slopes shows that they have a higher concentration and more intensive total impact on the northern part of the Bulgarian Black Sea coast, where most of the larger landslides are located. In this study, the Mora and Vahrson method was applied to estimate the landslide susceptibility along the northern Bulgarian Black Sea coast. This method is based on evaluation of various local factors for slope instability which are estimated using a Geographic Information System. The purpose of the study is to produce a landslide susceptibility map and to locate landslide-prone areas for this region.
