“…Additionally, there is a high probability that landforms such as rock creep or linear depression contours represent deformation of the rock, which is considered to be a signal that a deep-seated landslide will occur [e.g., Iwamatsu and Shimokawa, 1986;Wang et al, 2003].…”

A deep-seated rapid (catastrophic) landslide is a phenomenon that may cause serious damage due to the large amount of sediment movement, such as the formation of a landslide dam and debris flows. In Japan, a method for estimating deep-seated rapid (catastrophic) landslide susceptibilities for many small catchments (ca. 1 km 2 ) over relatively large areas (ca. hundreds of km 2 ) was proposed in 2008. In the present study, we applied the Japanese method to the northern part of Jember, East Java, Indonesia, where a debris flow disaster occurred due to the collapse of a landslide dam formed by a deep-seated rapid (catastrophic) landslide in 2004. Although there were several limitations related to data availability, we successfully assessed susceptibility to deep-seated rapid landslides.

“…The slip surface of the Chiu-fen-erh-shan area landslide ran parallel to the bedding plane, whose dip angles ranged 20-368 [3,[15][16][17]. Studies by Wang et al [3] and Hayashi et al [14] suggested that a slip surface can easily develop along a pre-existing bedding fault that was formed during flexural slip folding, and the strike as well as the dip of the local discontinuities generally governs the sequential slope failure. In addition, Kawabe [18] Figure 2.…”

“…In addition, the geological processes, which involve buckling, wedging, and thrusting on the slip surface immediately after the Chi-Chi earthquake, suggest that the area is susceptible to the reactivation of another landslide [3]. Therefore, assessing the constrained area of the unstable Chiu-fen-erh-shan landslide slope is a vital task to assist the authority dealing with further emergency managements.…”

SUMMARYChiu-fen-erh-shan landslide is a remarkable slope failure occurred during the Chi-Chi earthquake in 1999. In November of 2002, abnormal geomorphologic features, including buckling and ground subsidence, were observed on the lower slope of the Chiu-fen-erh-shan landslide. This study attempts to assess the constrained area of a future collapsing on the slope using a dynamic discrete numerical analysis method, discontinuous deformation analysis (DDA). The simulation results show that the depression in front of the toe of the slope provides a space for arresting the whole sliding rocks when only the unstable lower slope fails. However, as the whole slope slides, the rock fragments move farther into the memorial park and can impact other facilities resulting in the enlarging of constrained area. The authority should prohibit people from entrancing the constrained area in the rainy season.

“…For example, slip buckling slope failure was observed in a huge landslide triggered by 2008 Wenchuan earthquake shown in Fig. 1 and the Chiu-fen-erh-shan landslide triggered by Chi-Chi earthquake (Wang et al, 2003). However, the effect of earthquake on such failure mode has not been well understood by previous researches i.e.…”

Slip buckling failure often occurs in slopes intersected by a set of discontinuities with approximately parallel to the surface. Post-earthquake investigations indicate that some slip buckling failures occurred during 2008 Wenchuan event. However, it is still difficult to evaluate the slip buckling failure triggered by earthquakes. In this paper, we give a thorough mechanical analysis to slip buckling slope, and present an analytical solution on slip buckling slope failure which fully considers both the effect of earthquake and pore water pressure based on energy equilibrium theory. Then we apply the methodology to Tangjiashan landslide. Comprehensive retrospective study indicates that Tangjiashan landslide is a typical buckling failure case triggered by Wenchuan earthquake. The application shows that the analytical solution can be used to evaluate the stability of the slope with potential buckling failure during earthquake.
