Earthquake-induced landslides in the Tien Shan: where,when, and how big?
Recently,we compiled new and reviewed already existing landslide and earthquake data for a large part of the Tien Shan,Central Asia (Havenith et al.,in press,a).For the same area,only partial databases for sub-regions have been presented previously.Major new inputs are products of the Central Asia Seismic Risk Initiative (CASRI): a tentative digital map of active faults (even with indication of characteristic or possible maximum magnitude) and the earthquake catalogue of Central Asia until 2009that was now updated with USGS data (to May 2014).The new compiled landslide inventory contains existing records of 1600 previously mapped mass movements and more than 1800 new landslide data.Considering presently available seismo-tectonic and landslide data,a target region of 1200 km (E-W) by600 km (N-S) was defined for the production of more or less continuous geohazard information.This target region includes the entire Kyrgyz Tien Shan,the South-Western Tien Shan in Tajikistan and smaller parts in Uzbekistan,Kazakhstan and China (Figure 1).
