Landslide susceptibility mapping and modeling is critical in the understanding and consequent management of land resources. A study was conducted to ascertain the effect of an intrinsic soil property on landslide susceptibility mapping. Soil friction angle was added as instability factor in the form of PFAS (Peak friction angle – Slope) and RFAS (Residual friction angle – slope). These novel parameters replaced two traditional parameter; lithology and slope. Results indicated that PFAS and RFAS were significant additions and increased the predictive capabilities of the model.
