“…The quantification of consequences requires the identification of consequences and associating an expression of loss with them. This expression is usually in the form of a utility function [5], which is a dimensionless transformation that describes the relative preferences of the decision-maker toward different outcomes, as well as the decision-maker's attitude toward risk, i.e., risk neutral versus risk averse [34,50,55,59].…”

Landslides are one of the most vital natural hazards on Earth. To satisfy the demand for protection against landslides, it is necessary to systematically assess and manage landslide hazards and risk. Landslide mechanisms related to hydrology are analyzed with focus in the major risks, and formal risk assessment methodologies are presented in the paper. Issues related to risk assessment are discussed and different steps are described. The management of accidents in slopes is discussed, with particular emphasis to Hong Kong and Rio de Janeiro in Brazil. Hong Kong is a region of China with a large population density and very mountainous. There is a history of tragic accidents in the slopes. The territory has a tradition of a high standard in the practice of slope engineering. The establishment of an efficient security system developed by Geotechnical Engineering Office was established in the territory. Also, specific aspects of slope instability in the state of Rio de Janeiro are discussed, and in Rio de Janeiro city, with focus on cases which occurred in the mountainous region of the State. The mega-disaster that occurred in 2011, with high number of deaths and significant economic losses, is studied with incidence in individual landslides.

“…Usually, the quantitative risk assessment uses the Bayesian algorithm [6] . It calculates the probability of the factors, add or multiply the value to get the probability under certain condition [7] , but it is not good at internal analysis. Some quantitative risk assessment uses Rough sets based algorithm [8] , classifying the data according to the constructed function.…”

The assessment of potential risks posed by PH value in clothing to consumers is of increasing concern worldwide. If the PH value is too high, it is harmful to skin. Some papers focus on hazard assessment and exposure assessment, using quantitative and semi-quantitative method, rather than assessment for the factors related to the PH value. In order to perform early-warning research and risk management, the quantitative risk assessment is used in this paper to analyze the imported textile testing data and find the factors related to the PH value. The data mining technique and K-means algorithm is the core of the method. It can be concluded that the disqualified textiles have relations with main fiber components and fabric color. Then cluster the data by K-means algorithm for every factor, define the different class as related danger level, respectively severe, moderate, light.

“…Some of the major issues related to the analysis and management of rock slope instabilities are linked to "model uncertainties" (Einstein et al 2010). In particular, one important problem is to establish a method for appropriately combining relevant parameters for zoning purposes (i.e.…”

Rock fall hazard zoning is a challenging yet necessary task to be accomplished for planning an appropriate land use in mountainous areas. Methodologies currently adopted for elaborating zoning maps do not provide satisfactory results though, due to uncertainties and related assumptions characterising hazard assessment. The new Cadanav methodology, presented in this paper, aims at improving quantitative hazard assessment and zoning at the local scale, by reducing uncertainties mainly related to the technique for combining rock fall intensity and frequency of occurrence. Starting from available information on rock fall failure frequency and trajectory simulation results, the procedure merges in a strict way temporal frequency, probability of reach and energy data, and evaluates the hazard degree by means of "hazard curves". These curves are described at each point of the slope by a series of energy-return period couples representing the hazardous conditions which may possibly affect that location. The new Cadanav methodology is here detailed and compared to its original version. Hazard zoning results are illustrated along two different 2D slope profiles, for linear homogeneous cliff configurations, and according to the Swiss intensity-frequency diagram for rock fall hazard zoning. However, the procedure can be easily used with any other intensity-frequency diagram prescribed in national guidelines and, additionally, extended to problems involving 3D topographies.
