Abstract
Six events of landslides occurred simultaneously on weathered Andesitic Breccia in Samigaluh Area, following the heavy rainfall. Field investigation, laboratory works and slope stability analysis were carried out to assess the mechanism of the failures, their controlling factor and identify the triggering rainfall characteristics. It was found that the rainfall was the key factor inducing the failure. However, further investigation which incorporates slope hydrodynamic numerical modeling is still required, in order to find the triggering rainfall characteristics. In addition, the role of slope inclination was less significant than the soil and vegetation types covering the slopes. Finally, the landslide susceptibility map could be performed to support the prevention system.
