Abstract

The strong topographic relief and the presence of weakly consolidated sediments create favorable conditions for the development of mass movements in large areas of Central Asia. At the GFZ German Research Centre for Geosciences we are studying such gravitational mass movements in a multidisciplinary and both process-oriented and application-based way, focusing on better understanding of the triggering and motion-controlling factors. Development of automated remote sensing methods for spatial mapping and monitoring of mass movements using optical and radar remote sensing as well as Bayesian statistics and Geographic Information System (GIS) technology for regional hazard assessment are complemented by temporal monitoring of mass motion processes using seismological methods. The combination of novel passive seismic imaging technologies and the use of wireless sensors allows the rapid construction of inexpensive, spatially dense and self-organizing communication networks that can respond flexibly to changes and continuous data acquisition and transmission over long distances. In addition, geological field data can be used to identify potential shear zones and characterize their structural inventory, focusing on the question if climatic changes (i.e. changes in the mineralogical composition, microstructure and the pore water chemistry) will have effects on the shear strength of the rock and might, in consequence, trigger rapid mass movements.
