Earthquakes frequently induce landslides and slope failures which trigger many communities to be isolated. In this study, we proposed an estimation methodology for detecting isolated communities in mountain regions using slope failure probabilities during earthquakes. This methodology was constructed of the Structural Equation Modeling and the Logistic Regression Analysis using the disaster prevention charts and the stability survey tables. The SMOTE (Synthetic Minority Over-sampling Technique) was introduced for estimating slope failure probability more accurately by increasing the failure data equivalent to the non-failure one. Furthermore, we evaluated the community isolation risk in Wakayama prefecture based on the proposed road network disruption probability. Finally, we revealed the detecting method for the economic slope failure countermeasure sites in one sample case.
