“…The weak and incoherent flysch rock formations are strongly prone to deep-seated slope deformations (Pánek & Lenart, 2016) that are primarily triggered by heavy rains or rapid snowmelts (Krejčí et al, 2002;Pánek, Šilhán et al, 2011). Slope deformations of various types are the main geomorphic agent in the area (Pánek & Lenart, 2016) to such an extent that they affect particular slopes and entire mountain ridges repeatedly (Pánek, Šilhán et al, 2011).…”

The paper presents complex results of a dataset related to the pseudokarst caves in the area of the Czech Outer Western Carpathians. We collected the data from all 130 discovered and described caves of different types and dimensions in various geomorphic units and lithologies. We mainly focus on the results of the morphometric parameters of the caves as well as of the areas with their entrances. The final map sheet presents the Main Map with the position of the caves, their size category, type, classification of the position within the slope deformation and natural protection status. Moreover, the final map sheet also contains a supplementary map of the distribution of the caves, diagrams of their morphometric parameters, detailed maps of Mraznica and Cyrilka Caves, a graph of overwintering bat species in Cyrilka Cave and structural measurement diagrams. The map is intended to be used as introductory material into the problems of pseudokarst caves. ARTICLE HISTORY

The Èertovka land slide at Vaòov south of Ústí nad Labem, Czech Re pub lic, is de vel oped in a steep slope of the Labe River val ley (LRV). A ma jor ep i sode of landsliding oc curred in the first months of 1995, and the slope at Vaòov has been sub jected to geo log i cal and geomorphological in ves ti ga tion since then. This pa per pres ents the struc tural set ting of the Èertovka landslide based on the lat est geo log i cal sur vey, de tailed geomorphological map ping, morphostructural anal y sis and re sults of elec tri cal re sis tiv ity to mog ra phy. The land slide was found to be ini ti ated at the bound ary be tween Late Eocene to Oligocene ba saltic lavas above and volcaniclastics be low, with bed ding dip ping against the slope (anaclinal slope). The un der ly ing volcaniclastics show ten dency to argillization and have a much lower rock strength, which acts as an im por tant fac tor of slope in sta bil ity at the site. The Èertovka land slide is a com plex slope de for ma tion con sist ing of sev eral land slides and flowslides, with boul der streams merg ing into a boul der ac cu mu la tion fur ther downslope. The headscarp area of the landslide de vel oped at one of the struc tural lev els built by ba saltic lavas and form ing step-like mor phol ogy of the val ley slope. The headscarp co in cides with the course of a re gional E-W-strik ing Vaòov Fault that un der went mul ti ple tec tonic his tory and is as so ci ated with a dense frac ture sys tem in clud ing smooth slick en sides on the headscarp.

Abstract:We found ubiquitous evidence of ongoing slope instability by analysing the variability of tree-ring eccentricity index in trees growing on three apparently relict landslide slopes in the Sudetes (Poland, Central Europe). Slow movement of these landslide bodies occurs in the present-day conditions and is recorded almost every year, although with variable intensity. Correlation of dendrochronological record with the rainfall record from a nearby station in Mieroszów for the 1977-2007 period is very poor for two deep-seated rotational slides at Mt Suchawa and Mt Turzyna but considerably better for a shallow flowslide at Mt Garbatka. While this may reflect higher permeability of heavily jointed rocks involved in deep-seated sliding this could be linked with imperfections in the rainfall record. Dendrochronology proved capable of detecting minor displacements within landslides which otherwise show no geomorphic evidence of recent activity. Therefore, claims for the entirely relict nature of the landslides are not substantiated.
