Keywords:Landslide, Slope failures, AHP, Buffer movement analysis, Blunder probability analysis, Susceptibility map
The buffer analysis and blunder probability analysis using AHP method for making landslides and slope failures susceptibility map have been developed. This new analytic techniques for based on buffer movement and blunder probability is clarified relevant factors of landslide occurrences by both earthquake and heavy rainfall and facilitate risk assessment supplementing GIS.
The AHP method is the statistical technique for weighting the judgment items to create the susceptibility map
The Buffer movement analysis is the technique that collects GIS statistical data in the circles with radius R moving while skipping on the plan map.
The Blunder probability analysis is one of the objective functions to judge the compatibility of the landslide susceptibility mapping.
Author describe the methodology of these analysis and the results of AHP landslide susceptibility mapping as a case study on the landslides and slope failures by the 2008 Iwate-Miyagi Nairiku Earthquake.
