[1] The mechanisms that control climate-dependent rockfall from permafrost mountain slopes are currently poorly understood. In this study, we present the results of an extensive rock slope monitoring campaign at the Matterhorn (Switzerland) with a wireless sensor network. A negative dependency of cleft expansion relative to temperature was observed at all clefts for the dominant part of the yea...

Landslides associated with hillside cuttings in igneous rock saprolites are a serious natural hazard in Hong Kong and have been extensively studied by government agencies and local universities for many years from the perspective of soil and rock engineering. A review of the case studies for some major landslides, especially deep-seated landslides, shows certain puzzling features. First, a numb...

Quantitative classification from the Slope Mass Rating (SMR) has introduced an empirical assessment for rock slope stability rating. This enables us to foreseethe magnitude and susceptibility of mass failure towards adjacent infrastructure human life. In this study, quarry was classified using SMR system kinematic analysis before being correlatedwith geohazard vulnerability assessment. Geologic...

This paper presents an application of a recently developed methodology for the identification and analysis of flat surfaces affecting rock masses using 3D LiDAR point clouds(Riquelme et al., 2013 submited). The used methodology has been applied to calculate the algebraic equations of the different discontinuities of a rock slope through a methodology based on next three steps: (a) local curvatu...

Figure 1. Extent of widespread Osceola Mudflow and Electron mudflow deposits from Mount Rainier. These deposits contain hydrothermally derived clay minerals and likely originated from flank collapses. Modified from Scott and Vallance (1995) and Vallance and Scott (1997). ABSTRACT Catastrophic collapses of steep volcano flanks threaten many populated regions, and understanding factors that promo...

In slope stability analysis, the limit equilibrium method is usually used to calculate the safety factor of slope based on Mohr-Coulomb criterion. However, Mohr-Coulomb criterion is restricted to the description of rock mass. To overcome its shortcomings, this paper combined Hoek-Brown criterion and limit equilibrium method and proposed an equation for calculating the safety factor of slope wit...
