Abstract

This study aims to study and map landslide agencies in the city of Manado in the aftermath of the 2014 Flash floods disaster. Landslide hazard mapping is based on physical factors and trigger factors for landslides. The method used is quantitative descriptors, which begins with an analysis of maps and aerial photographs, data collection is done through observation, field measurements, and laboratory analysis. Data were analyzed by means of field parameters and based on the results of the analysis showed that landslides in the city occurred due to physical factors such as slope, soil texture, soil permiability, soil solum thickness, weathering of rocks, percentage of steep walls, land use, vegetation density, outside drainage and Deep drainage in addition to the trigger factors, namely high rainfall and land use contribute to landslides. Based on the results of the analysis and mapping of landslides, in the city of Manado, there were three landslide hazard levels, namely low, moderate and high landslide hazard levels.
