“…3c). Here, the bulk of mass movement occurred within a broad valley floor and the most likely mechanism was a flowslide initiated by a shallow translational slide at the valley head which left a shallow slope hollow (Migoń et al, 2014). Thus, the valley floor is filled by a colluvial package with numerous floating boulders probably up to 10 m thick on the proximal side, thinning to a few metres in the distal, fan-like side.…”

“…Subdued surface morphology, the absence of any distinct toe, and the presence of well developed soils within the landslide terrain suggest a considerable age of the main phase of mass movement on the slopes of Mt Garbatka (Migoń et al, 2014). Whether the landslide is entirely relict or shows signs of instability is debatable.…”

“…The landform assemblage indicates that the primary mechanism was a flowslide and the geophysical survey showed that the basal detachment surface is at most 10 m below the surface (Migoń et al, 2014) and furthermore, the landslide body occupies a valley floor which tends to receive additional water from the surrounding slopes. However, although the landslide itself originates in porous rhyolitic tuffs and the top part of colluvial materials (up to 2 m) often show an openwork structure, favourable conditions for waterlogging and pore-pressure changes at greater depth may occur.…”

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.

“…Many landslide episodes were dated on the basis of dendrochronological measurements, both within the Western Carpathians (Krąpiec, Margielewski 2000, Wistuba et al 2013, Šilhán 2012, 2016 and in the Sudetes (Malik, Owczarek 2005, Wistuba et al 2012, Migoń et al 2014). The dendrogeomorphology method also allows for dating other processes: debris flow (Malik, Owczarek 2009, Šilhán et al 2015, bank erosion (Milik, Matyja 2008), gully erosion (Malik 2008), rockfall (Stoffel, Perret 2006, Zielonka, Dubaj 2009), root erosion (Malik, Owczarek 2005, Buchwał, Wrońska-Wałach 2008, flooding (Wistuba 2008, Ballesteros-Canovas et al 2015, volcanology (Bollschweiler et al 2010, Franco-Ramos et al 2013.…”

Abstract:The article presents the results of the dendrogeomorphological study of the activity of the Sawicki landslide, located in the Beskid Niski Mts (Polish Flysch Carpathians). The study was conducted within two study sites in the lower part of the landslide. The landslide movements were dated using the dendrogeomorphological method, basing on the eccentricity indicators calculated for the two coniferous species, i.e. Scots pine (Pinus sylvestris) and silver fir (Abies alba). It was found landslide activity in years: 1899, 1901, 1905, 1910, 1913-1914, 1920-1921, 1929-1931, 1935, 1937, 1945, 1977, 1979, 1981, 1984-1985, 1990, 1992-1993, 1997, 2003-2004, 2006, 2010-2012. The greatest activity was characterized for the northern part of the study site B and the south-western slopes of the Szklarki stream valley (study site A). Studies have shown only a partial dependence between precipitation and landslide episodes. The data were confronted with the results of dendrogeomorphological studies, conducted in the northern and central parts of the landslide. The results demonstrate the significant complexity of mass movements within large-area landslide.

Dendrogeomorphic chronologies of landslides: Dating of true slide movements?

Dendrogeomorphic chronologies of landslide movements are frequently used to investigate past landslide activity. Slide areas are often affected by other slope movements (e.g. creep) simultaneously. Trees growing on landslides record all types of ground movements, which potentially creates significant noise in tree ring based chronologies of landslide movements. The effect of creep movements on dendrogeomorphic landslide chronologies was evaluated in a block-type landslide in the south-western foreland of the Orlické hory Mountains. In total, 272 trees (Picea abies and Fagus sylvatica) were sampled (1088 increment cores) on the sub-horizontal surfaces of rotated slide blocks, which were presumably created only by slide movements, and on the steep internal scarps separating landslide blocks, which were presumably created and affected by a combination of slide and creep movements. Ground movements were dated based on growth disturbances identified in an analysis of eccentric tree growth.The trees growing on the internal landslide scarps separating the rotated blocks exhibited a significantly higher number and frequency of growth disturbances than those growing on the sub-horizontal block surfaces. All eight dated block surface movements were also identified on the internal scarps. Creep-based events represented as many as 70% of the dated movement events on the internal scarps. Varying the I t thresholds did not filter out more than 40% of the noise without significantly reducing the number of true dated slide events. A significant difference was observed between the ability of P. abies and F. sylvatica to record ground movements by eccentric growth. Probably due to its shallower roots (and weaker anchoring of the tree to landslide blocks), P. abies appears to be more sensitive to surficial ground movement, which potentially increases the proportion of dated creep events (noise). Thus, the careful selection of sampled tree species with different physiologies should be considered during dendrogeomorphic field sampling.
