[HDS07-P08] Implementation of Selection Criteria to Improve Landslide Susceptibility Model of Kashiwazaki-Kariwa, Japan: a Frequency Ratio Approach
Keywords:Landslides, Logistic Regression, Frequency Ratio Approach
The landslide susceptibility model of Kashiwazaki-Kariwa in this study was produced involving the morphometric, geological, land use–land cover, and landslide distribution data. The data were acquired from open-source domains, ASTER Global DEM of NASA’s Jet Propulsion Laboratory, Geological Survey of Japan (GSJ), Japan Aerospace Exploration Agency (JAXA) Centre for Earth Observation Research (EORC), and National Research Institute for Earth Science and Disaster Prevention (NIED) of Japan respectively, which were prepared on the Geographic Information System (GIS) platform.
More than 120 models generated from seven predisposing factors, and compared using the values of LSI, the area under the receiver operating characteristic-ROC (AUC), and accuracy. The model consists of elevation-slope-profile curve-geological feature-Land use showed the most reliable performance with the value of 1.0482 (LSI), 0.8074 (AUC) and 75.13% (Accuracy).
