Abstract

 In the present study, landslides occurred during 1997 Sarein, Iran EARTHQUAKE are discussed and evaluated. In order to meet the objectives, the Computing with Words (CW), an approach using FUZZY LOGIC systems in which words are used in place of numbers for computing and reasoning is applied. Firstly, the necessary information which include disturbance distance, ground class, moisture, shaking intensity, slope angle, slope height, soil depth, terrain roughness, and land-use have been collected using air photos, LANDSAT satellite images, geological and topographic maps, and site investigation of the studied region. The data is digitized and weighted using ARCGIS software. At the next step, the hazard rate and predicted areal concentrations of landslides with respect to their types are calculated using CAMEL software (Miles & Keefer, 2007). CAMEL provides an integrated framework for modeling all types of EARTHQUAKE-induced landslides using geographical information system (GIS). Finally, landslides hazard map is compared to landslides triggered by Sarein EARTHQUAKE.
