“…The weak layers mainly include coal seams, thin carbonaceous shales, mudstones and claystones (Wang et al, 2008). A typical example is the dangerous rockmass in Lianziya town, 27 km upstream from the Three Gorge Dam where massive limestone Qixia group is intercalated with weak coal seams of the Liangshan group (Wang et al, 2006;Peng et al, 2009). Another example is the 2003 Qianjiangping landslide which occurred shortly after the water level rose to 135 m following the first impoundment of the Three Gorges Reservoir.…”

“…The research was aimed to reassess the rockfall risk on a cliff-top settlement, and to implement a surveillance system for cliff instability. Peng et al (2008) inventoried rock mass on cliff alongside the valley of China's Three Gorges River, in relation with risk mapping of landslide and rockfall. It was concluded from this research that the biggest factors that control cliff stability of rock mass in Three Gorges River are the layering and structure of the rock mass.…”

On 17 th of June 2015, rockfall occurred on the South Coast at Gunung Kidul Regency taking a few casualties. The preliminary investigation results concluded that many cliffs on the South Coast are dangerous, and there is a potential that similar events might happen in the future. Therefore, geotechnical investigation in order to plan mitigation action is necessary. Field investigations, laboratory work, and numerical modeling were employed in this study, focusing on Sadranan beach where the incident happened. Rock slope stability analyses by means two-dimensional finite element in both static and seismic conditions were conducted. The investigation results show that both biological decay and wave erosion influence the rock slope instability. Moreover, the infilling material in rock joint has considerable effect on the stability of the slope. However, the results from numerical simulation suggested that potential failure was originating from the intact rock body instead of the plane of discontinuities. In the seismic condition, the slopes are more vulnerable and further mitigation action should be considered in the future.
