Structurally controlled slope movements in the eastern section of Moravskoslezské Beskydy Mts., Czech Republic
Abstract
Investigations of slope movements in a mountainous terrain of the eastern section of Moravskoslezské Beskydy Mts. resulted in preparation of inventory engineering geological stability condition maps on 6 map sheets 1 : 10 000 and derived prognostic landslide susceptibility maps. Pre-Quaternary bedrock is formed by Flysch sandstones and claystones of Silesian nappe that are represented mostly by Godula Formation, partially also by Istebňa Formation. In the investigated region moderate inclination of layers to S is characteristic and responsible for asymmetric development of slopes. Southern slopes show more moderate inclination being frequently deformed by large translational block-type creep (spread) movements and bedding controlled landslides. On the other hand slopes oriented to N are usually steeper being deformed by deep-seated landslides along compound shear planes, deep slope loosening by inter-layer creep, debris-flows, minor mud flows and rock falls.
