Deep-seated gravitational slope deformations in the highest parts of the Czech Flysch Carpathians: Evolutionary model based on kinematic analysis, electrical imaging and trenching

“…rock avalanches, debris flows, and rockfalls) is still an open question despite some documented cases (e.g. Kilburn and Petley, 2003;Brideau et al, 2005;Geertsema et al, 2006a,b;Pánek et al, 2009b;Kellerer-Pirklbauer et al, 2010). Our case studies reveal a narrow spatial correlation of DSGSDs both with shallow (b10 m) and deep-seated (N30 m according to Hutchinson, 1995) landslides .…”

“…Despite general agreement on low probability of catastrophic event evolution (Hewitt et al, 2008), some historical rockslides and rock avalanches originated on slopes which had gradually been deformed for thousands or more years, as it was described by e.g. Kilburn and Petley (2003), Brideau et al (2005), Geertsema et al (2006a,b) or Hewitt et al (2008).…”

Time constraints for the evolution of a large slope collapse in karstified mountainous terrain of the southwestern Crimean Mountains, Ukraine

“…Korup, 2006), stress relationships between rock mass anisotropy and geometry of sliding surfaces (e.g. Brideau et al, 2005;Margielewski 2006a) and try to constrain chronology of their evolution (e.g. Alexandrowicz and Alexandrowicz, 1999;Soldati et al, 2004;Margielewski 2006b;Pratt-Sitaula et al, 2007).…”

Staring Spotlight TerraSAR-X SAR Interferometry for Identification and Monitoring of Small-Scale Landslide Deformation

“…The second inset shows another similar active part of the landslide. The concentration of the regional tectonic features, such as faults and shear zones (Figure 9), which reduce the quality of rock mass [11], can cause onset of rockfalls or slides compatible with the deformation pattern observed in the interferogram. The third inset shows subtle movement in the accumulation zone of the Hope Slide, where the debris of the historic landslide has accumulated and created a bulge.…”

“…The landslide buried Highway 3 under 47 million cubic meters of rock [9]. Seven faults and three dominantly brittle shear zones, along with tension cracks and trench-like features, have been recognized as the main deformation features in the Hope Slide area [10,11]. The aforementioned geological features, along with the historical landslide in the Hope Slide, draws attention to using the TSX-ST images to perform a comprehensive analysis of slope stability on and around Hope Slide, to better understand the triggers and dynamics of mass movements in the area.…”
