DESIGN OF APPLICATION ARCHITECTURE FOR SPATIAL INFORMATION BASED VOLCANIC DISASTER RESPONSE SYSTEM

The prediction of the size of rainfall-induced debris in South Korea was analyzed. The model suitability was carried out and Random forest was the most suitable for the Size of debris prediction. The most contributing factor in the model was slope length and the most vulnerable region to higher frequency and severe debris was Gangwon province. The findings may be used for rainfall induced-debris prevention policies and post-disaster rehabilitation planning.
