This paper aims to propose an ensemble method of frequency ratio (FR) and logistic regression (LR) in order to overcome their weak points. For landslide susceptibility mapping (LSM), a landslide inventory map with a total of 87 landslide locations was extracted from various sources. Then the landslide inventory was randomly divided into 2 datasets 70% for training the models and the remaining 30% was used for validation purpose. The impacts of various pick ground accelerations (PGA) on landslide occurrences were analyzed. The resultant maps were then validated using area under the (ROC) curve. Additionally, most influencing conditioning factors on landslides were assessed. The proposed ensemble method gave reasonable good accuracy
