Reconstruction of landslide movements using Digital Elevation Model and Electrical Resistivity Tomography analysis in the Polish Outer Carpathians

摘要: Abstract Landslides are a major threat to the environment, infrastructure and human activities, especially in mountainous hilly areas. It is therefore important accurately identify mass movements triggering these mechanisms. This paper presents impacts of lithotectonic conditions on formation example landslide that located northern part Polish Outer Carpathians. In area research, ratio total landslides surface reaches even 20%. The interpretation high resolution Digital Elevation Model (DEM), Electrical Resistivity Tomography (ERT) fieldwork results allowed for reconstruction dividing them into two areas; western one, dominated by rotational movement, eastern featuring translational movement. was found more active now as it probably also past, which might have resulted from conditioned or impact flowing waters Dunajec River. Moreover, landslides, small-sized ridge (55 m × 25 m) identified, shows greater stability comparison with colluvium surrounds it. order explain lower rate movement this landform, morphometric analysis research using ERT were performed. geophysical measurements showed comprised rock formations resistivity than its surroundings. most likely only preserved sandstone packet, constituting original secondary escarpment, became separated bedrock due presented studies indicate created geological atmospheric conditions. A clear revival took place after significant precipitation events last occurred years 2010 2015. substrate lithology tectonics, facilitates movements. studied complex entity, characteristic Carpathians, has undergone multiple stages development. periodically and, therefore, must be excluded planned development well other forms activity.
