Comparison of two landslide hazard zonation methods in the volcanic terrain of Temanggung Regency, Central Java, Indonesia

Landslides are a recurring phenomenon that disrupts the natural environment and causes yearly property damage, economic losses, fatalities. The damage is expected to increase due deforestation rates, population growth, agriculture, slope-building infrastructure expansion, global climate change. This study assesses susceptibility landslides through Weight of Evidence (WoE) Frequency Ratio (FR) methods in Temanggung Regency, Central Java Province, Indonesia, located on slopes two active volcanoes. Initially, landslide record input parameters controlling factors were prepared from field surveys, remote sensing data, secondary data processed by geographic information system (GIS). Six thematic layer maps selected develop susceptibility: slope, lithology type, geological structure density, land cover, rainfall. According WoE FR models, zoning map was classified into four landslide-prone zones low very high. Finally, success predictive rate curves method confirmed check model accuracy. results showed using had better accuracy than method, with 78.48% prediction 81.1%. In comparison, 74.53% for rate. These can be used as guideline land-use planning disaster mitigation.
