Recurrent Holocene landslides: a case study of the Krynica landslide in the Polish Carpathians

Abstract

Situated in the southern part of the Polish Outer Carpathians, the development of the Krynica lanslide is presented in detail. Head scarps, slide shoulders and colluvial ridges connected with particular episodes of sliding occur on the western slope of the Parkowa Góra Mountain. Peaty silts and calcareous tufa suitable for the radiocarbon dating fill depressions within colluvial masses. Calcareous deposits contain rich assemblages of molluscs characterizing changes of the climate and the environment during the Late Vistulian and the Holocene. Four stages in the evolution of the landslide correspond with phases of increased mass movements distinguished elsewhere in the Carpathians according to radiocarbon dating as well as palynological and malacological analyses. The phases of enhanced mass movement correlate in turn with climatic changes.

Late‐glacial and Holocene river development in the Teleorman Valley on the southern Romanian Plain

“…5). All these periods of alluvial sedimentation correlate well with periods of climatic cooling, increased humidity and enhanced fluvial activity (flood frequency and magnitude) recorded elsewhere in central, northern and western Europe (Macklin and Lewin, 1993;Starkel, 1995;Kalicki, 1996, Rumsby andMacklin 1996) and other geomorphological records, including landslide activity in the Carpathian Mountains (Alexandrowicz and Alexandrowicz, 1999) and bog oak chronologies in Germany (Spurk et al, 2002). Phases of calcium precipitation and cementation of alluvial sediments in the Teleorman Valley could relate to a number of these wetter phases, with calcareous precipitation recorded in Poland, for example, before 5000 yr BP and between 4100 and 3200 yr BP (Starkel, 1995).…”

“…G. Passmore et al, University of Newcastle, unpublished). River activity in some of these latter systems has been linked to climatic change through correlation with other geomorphological proxy records including lake-level and glacier fluctuation data in the Alpine zone, landslides in the Carpathians (Starkel, 1995;Kalicki, 1996;Alexandrowicz and Alexandrowicz, 1999) and raised bog stratigraphies in the UK (Macklin, 1999).…”

Structure and dynamics of deep-seated slope failures in the Magura Flysch Nappe, outer Western Carpathians (Czech Republic)

“…All of the studied case sites for deep-seared failures are of prehistoric age. It is presumed that they originated during the humid phases of Early Holocene or during the Late Glacial as permafrost began to melt (Alexandrowicz and Alexandrowicz, 1999;Margielewski, 2002). The amount of water available in such conditions would have been much larger than that associated with the anomalous precipitation event of July 1997, when a relatively sporadic and isolated activation occurred within at the study sites.…”
