Analysis of landslide susceptibility in the Suusamyr region, Tien Shan: statistical and geotechnical approach

摘要: The Suusamyr region is located in the northern part of Tien Shan Range Central Asia. In 1992, this was hit by Ms = 7.3 earthquake triggering several large landslides along Valley and on southern slopes adjacent Range. One these had been investigated geophysical geotechnical methods order to determine local trigger factors. present paper focuses influence geological morphological factors upon landslide occurrence a regional scale. analysis based digital data set including triggered 1992 older as well various types elevation models (DEMs), ASTER image data, active fault maps. These were combined compute susceptibility (LS) maps using statistical methods, Landslide Factor Conditional Analyses (LFA, CA), one, Newmark's Method (NM). also analyzed with respect size–frequency relationship.
