Landslide Susceptibility Mapping in the Vrancea-Buzău Seismic Region, Southeast Romania

This study presents the results of a landslide susceptibility analysis applied to Vrancea-Buzău seismogenic region in Carpathian Mountains, Romania. The target area is affected by large diversity processes. Slopes are made-up various types rocks, climatic conditions can be classified as wet, and seismically active one. All this contributes observed high hazard. paper analyses spatial component hazard affecting area, regional susceptibility. First, an existing inventory was completed cover wider for analysis. Second, two methods applied, purely statistical technique, based on correlations between occurrence local conditions, well simplified process-based Newmark Displacement Landslide maps have been produced applying both methods, second one also allowing us simulate different scenarios, soil saturation rates seismic inputs. Furthermore, computed source runout zones—the first providing information about areas where landslides preferentially triggered indicating move along slope accumulate. showed that any produces reliable However, uncertainties were outlined validation insufficient, especially northern only few could mapped due intense vegetation cover.
