“…Dobos et al (2005) recommended deriving morphometric data from a 90 m SRTM and then resampling it to 990 m resolution for delineating SOTER (World SOil and TERrain Digital Database) Terrain Units. Korup et al (2007) studied the relation between giant landslides and topography using SRTM30 as a base DEM. A measure of local relief (maximum elevation minimum elevation) was used instead of local slope due the substantial underestimation of slope by SRTM30 data.…”

This paper investigates differences between morphometric parameters (slope and aspect) derived from a resampled DEM and resampled morphometric data derived from a medium resolution DEM, with examples for three study areas in South America selected to represent flatlands, hilly terrain, and mountain ranges. Using a low resolution DEM for regional scale morphometric analysis is not an optimal choice, since attenuation of elevation will strongly affect the distribution of calculated parameters. Unless bounded by computational constraints, one should choose to derive basic morphometric parameters from higher resolution data, and resample it to a coarser resolution as needed.

“…All over the world, in mountains with huge altitude difference and intense rainfall, landslides and debris flows frequently take place and are the major geological hazards [1][2][3][4][5], such as in the surrounding areas of the Tibetan Plateau. The Upper Yellow River, that locates in the northern part of the Tibetan Plateau and consists of four basins areas (i.e., Guide, Jianzha, Xunhua and Guanting) from Longyangxia Gorge to Shigouxia Gorge, is such a geological disaster-prone area ( Figure 1).…”

“…In active mountain ranges, landslides are an important process in long-term erosion and thus contribute to the geomorphologic evolution of relief (Korup et al, 2007). Despite their importance in terms of hazards, landslide maps remain rare (Guzzetti et al, 2012) and information on the type, age or distribution of individual landslides is often lacking.…”

Tectonic and climatic controls on the Chuquibamba landslide (western Andes, southern Peru)

Abstract. The contribution of landslides to the Quaternary evolution of relief is poorly documented in arid contexts. In southern Peru and northern Chile, several massive landslides disrupt the arid western Andean front. The Chuquibamba landslide, located in southern Peru, belongs to this set of large landslides. In this area, the Incapuquio fault system captures the intermittent drainage network and localizes rotational landslides. Seismic activity is significant in this region with recurrent M w 9 subduction earthquakes; however, none of the latest seismic events have triggered a major landslide. New terrestrial cosmogenic dating of the Chuquibamba landslide provides evidence that the last major gravitational mobilization of these rotational landslide deposits occurred at ∼ 102 ka, during the Ouki wet climatic event identified on the Altiplano between 120 and 98 ka. Our results suggest that wet events in the arid and fractured context of the Andean forearc induced these giant debris flows. Finally, our study highlights the role of tectonics and climate on (i) the localization of large Andean landslides in the Western Cordillera and on (ii) the long-term mass transfer to the trench along the arid Andean front.
