Research Abstract

Slopes on which valley creeping type landslide is occurring are prone to persistent rainfall-induced landslides. Identification of these slopes is therefore an important consideration when mapping landslide susceptibility and preparing for landslide risk management. In this study, we investigated the use of resistivity data to identify slopes on which valley creeping type landslide is occurring.
