“…The current practice in Europe (Corominas et al 2010) shows that the scale of the landslide zoning maps required by state or local authorities varies significantly from country to country, depending on the coverage, input data and methods that are used as well as the information provided (qualitative or quantitative).…”

This paper presents recommended methodologies for the quantitative analysis of landslide hazard, vulnerability and risk at different spatial scales (site-specific, local, regional and national), as well as for the verification and validation of the results. The methodologies described focus on the evaluation of the probabilities of occurrence of different landslide types with certain characteristics. Methods used to determine the spatial distribution of landslide intensity, the characterisation of the elements at risk, the assessment of the potential degree of damage and the quantification of the vulnerability of the elements at risk, and those used to perform the quantitative risk analysis are also described. The paper is intended for use by scientists and practising engineers, geologists and other landslide experts.

“…Some of them are intended to be introduced into legislated standards (OFAT, OFEE, OFEFP 1997;AGS 2007). However, the methodologies implemented diverge significantly from country to country, and even within the same country (Corominas et al 2010).…”

“…They can be tilted even during very slight ground movements (Malik and Wistuba, 2012) and, after tilting, develop eccentric annual rings which help us to date landsliding events (Braam et al, 1987;Filion et al, 1991;Fantucci and McCord, 1995;Stefanini, 2004;Corominas and Moya, 2010). In response to stress trees produce normal, reaction, opposite and eccentric wood (e.g.…”

Activity of Slow-Moving Landslides Recorded in Eccentric Tree Rings of Norway Spruce Trees (<i>Picea Abies</i> Karst.) — An Example from the Kamienne MTS. (Sudetes MTS., Central Europe)

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.

“…He studied 800 landslides in Japan caused by heavy rainfall [9][10][11]. The cumulative number is calculated by using the area or a combination of area and volume of landslide triggers [12][13][14][15][16][17][18][19][20]. Other studies have been made using only the volume of landslides [9,21,22].…”

This study aims to assess the localization and size distribution of landslides using automatic remote sensing techniques in (semi-) arid, non-vegetated, mountainous environments. The study area is located in the Kurdistan region (NE Iraq), within the Zagros orogenic belt, which is characterized by the High Folded Zone (HFZ), the Imbricated Zone and the Zagros Suture Zone (ZSZ). The available reference inventory includes 3,190 landslides mapped from sixty QuickBird scenes using manual delineation. The landslide types involve rock falls, translational slides and slumps, which occurred in different lithological units. Two hundred and ninety of these landslides lie within the ZSZ, representing a cumulated surface of 32 km 2 . The HFZ implicates 2,900 landslides with an overall coverage of about 26 km 2 . We first analyzed cumulative landslide number-size distributions using the inventory map. We then proposed a very simple and robust algorithm for automatic landslide extraction using specific band ratios selected upon the spectral signatures of bare surfaces as well as posteriori slope and the normalized difference vegetation index (NDVI) thresholds. The index is based on the contrast between landslides and their background, whereas the landslides have high reflections in the green and red bands. We applied the slope threshold map to remove low slope areas, which have high reflectance in red and green bands. The algorithm was able to detect ~96% of the recent landslides known from the reference inventory on a test site. The cumulative landslide number-size distribution of automatically extracted landslide is very similar to
