Abstract

First landslide hazard zonation provided based on Fuzzy logic by landslide area laid on the Slope map, ‎Geology( lithology) map, Aspect map. Then, these maps classes of priority and coming next determine based ‎on existing landslides area in the geology, slope, and aspect of maps. In the geology map of tuff, shale, and ‎conglomerate rocks, about with hectare 1440.43(about percent 23.94 ) and shelly limestone ‎‎ about with hectare ‎‎0.88 (about percent 0.01 ) and in the slope map, X>45 classes about with hectare 2794 ( about percent 46.44 ) ‎and 15-25 classes about with hectare 737 ( about percent 12.25) and in the aspect map, East classes with about ‎hectare 1882 ( about percent 31.28 ) and west classes with hectare 579 ( about percent 9.62 ) sequential have ‎most and least landslide area. Then, in the final drawer to dimension centimeters 2 in region watershed ‎management of map and we counted from 0 until 863 based on geology, slope and aspect that exist the only unit ‎‎624 counted from 0 until 623. Then (y) units settled sequential, numbers 0 to 105 in very low sensitivity class ‎‎(one class), numbers 106 to 207 in low sensitivity class (two class), numbers 208 to 345 in average sensitivity ‎class (three class), numbers 346 to 498 in high sensitivity class (four class) and numbers 499 to 623. then ‎landslide hazard zonation provided a base on Fuzzy logic.‎
