Abstract
The identification and assessment of the threat of ground motion need to be carried out with a combination of knowledge from field observations to visually identify the existing drainage system, slope, and analysis of the intensity of rainfall that causes infiltration and the geological conditions of the area. The assessment method uses aerial photography, geological observations, and research experience in ancient volcanic rock areas. The results of data processing show that the Baturiti District was an area that is prone to landslides because there are cavities with quite weathered rocks due to the overflow of ancient Buyan-Beratan Mountain with a thickness of 10-15 meters. Analysis of geological units and soil types was weathered rock or sandy silt sedimentary soil. The landslide trigger shows the slope between 60o – 70o, the road drainage wasn't good, the occurrence of additional vibration loads due to high traffic volume and increased rainfall intensity where the pore water pressure increases, the loose soil will be easier to escape.
