Identification of Landslide Disaster Potential based on Weathering Grade of Rock in Parepare City South Sulawesi, Indonesia

Abstract

Abstract The purpose of this research is to identify the potential of landslide disaster based on weathering grade of rocks from selected areas. There are three aspects of field observation method used in this research, consist of slope geometry, lithology, and weathering grade of rocks aspects. The result shows that the rocks on research area have been slightly to completely weathered, some areas have became residual soil and slope angles of the research area varieties from steep to very steep. With those condition of weathering and slope angle, the research area will be slightly to very susceptible to landslide. The landslide models or types that will occur are debris slide and debris fall.
