A chronology of landsliding based on archaeological and documentary data: Pavlovské vrchy Hills, Western Carpathian Flysch Belt
Pavlovské vrchy Hills represent a distinctive elevation near the Czech-Austrian border where the active, dormant and relict landslides cover 12% of the area. Here we focused on the chronology of landsliding in this area using geological, archaeological and historical evidence. The earliest records of landsliding were determined in locations underlying the dated archaeological settlements. The Upper Paleolithic settlement complex dated between 37–24 ka cal BP, was originally deposited over these landslides. It was consequently destroyed in certain places by additional landslides preceding the last (Upper Pleniglacial) loess deposition (22 ka cal BP). These landslides took place before and after the Upper Paleolithic occupation of this area. This Pleistocene landslide event ranks among the oldest (albeit indirectly) dated landslide within the Czech part of the Western Carpathian Flysch Belt. The chronology of later, historical, landsliding was determined using written records (chronicles, official reports, archival evidence, etc.). Continuous records of landsliding were available as of the middle of the seventeenth century. The major concentration of landslides occurred at the beginning of the twentieth century (1910–1915). The 1663 landslide is currently the oldest landslide, in the Czech part of the Western Carpathian Flysch Belt, which was dated on the basis of documentary data.
