“…(3) distinct changes in hillslope drainage density and dissection; (4) asymmetric lakes or ponds on valley floors; and (5) abrupt changes in channel-reach morphology (van Westen et al, 2008). In order to estimate the volume of debris contained in the 492 landslides in our data set, we derive a scaling relationship between volume and area from published data on landslide volume and area for the Himalayan orogen, drawing on 114 published data (Ibetsberger, 1996;Walder and O'Connor, 1997;Hewitt, 1998;Shroder, 1998;Fort, 2000;Hodges et al, 2004;Weidinger, 2006a;Weidinger, 2006b;Mitchell et al, 2007;Hewitt et al, 2008;Dortch et al, 2009;Hewitt, 2009;Hewitt et al, 2011;Weidinger et al, 2014). We obtained a scaling relationship of the form V = bA s , where V is volume We acknowledge that our inventory covers only part of the potentially heavy-tailed distribution of hillslope mass wasting in the Himalaya-Karakoram Ranges (HKR).…”

ZusammenfassungDie gewonnen geologischen, geomorphologischen und geotechnischen Grundlagenerkenntnisse an der im Kristallin weltweit gewaltigsten und einzigartigen Großmassenbewegung des Tsergo Ri im Langthangtal des zentralen Nepal Himalaya entschlüsselten nicht nur den chronologischen Ablauf der Paläo-Ereignisse vor Ort, sondern können auch direkt auf eine Einstufung des rezenten Gefahrenpotentials dieser Gegend und ähnlich geotektonisch-lithologisch positionierter Bereiche des Himalaya und der Erde angewendet werden. Dies konnte vorerst am Beispiel weiterer, kleinerer Bergstürze im Langthangtal selbst, im Kristallin des Annapurna Massivs und mit einem Vergleich zu einer Felslawine in Zentralchina bestätigt werden.

Detailed investigation of Taprang landslide was carried out in order to understand the surface, subsurface lithological information and physical properties of soil by using multi-disciplinary methods such as engineering geological, geophysical and geotechnical studies for the determination of factor of safety for slope stability analysis. Geological study was carried out by detail mapping of surface geology, soil condition, properties of bedrock and its discontinuities. The geophysical survey (Electrical Resistivity Tomography-ERT) were carried out to know the electrical resistivity of soil for identifying the groundwater table and hence slip surface of the landslide. Geotechnical analysis such as grain size analysis, liquid limit and direct shear test were carried out in order to evaluate soil classification, moisture content, cohesion and the angle of internal friction of soil for knowing the strength the soil. These soil parameters indicate the soil is very low strength. The combination of these results were used for calculating the factor of safety (FoS) by Limit Equilibrium Method (LEM) proposed by Bishop and Janbu methods. The result of factor of safety in the Taprang landslide demonstrates that the slope become stable in drained (dry) condition, remain ultimate stage in undrained (wet) condition and finally failure occurs if applied the seismic load in both drained and undrained conditions.
