A methodology for scenario-based, quantitative estimation of regional-scale vulnerability is proposed. Susceptibility refers to the lack of inherent capacity of the elements in the spatial extension under investigation to preserve their physical integrity and functionality in the course of the physical interaction with a generic sliding mass.
The susceptibility S of any category of elements at risk ranges from 0 (no susceptibility) to 1 (maximum susceptibility).
Landslide intensityHungr (1997) concisely and effectively defined landslide intensity as ?a set of spatially distributed parameters describing the destructiveness of a landslide?. A composite landslide intensity parameter, accounting for kinetic and kinematic characteristics of the interaction between the sliding mass and the reference area is proposed. Any kinetic intensity parameter may be defined by the user provided it is defined in the range [0,1] with unit values indicating maximum intensity.
Here susceptibility expresses the likelihood that a landslide will occur in an area on the basis of the local terrain conditions. Method of studyAn empirical approach was used to map and evaluate landslide susceptibility. This case study is intended to illustrate the meaning of hazard, vulnerability and risk, using a very simple data set on the national-scale of Colombia (South America).
Then, attribute maps of the weight values are derived from all these maps; these are the first factor maps. Further, with mapcalc, factor maps are obtained from maps on inundation hazard, rivers, and for altitudes above 1000m. First, the population density of each department (province) in Colombia is calculated in a table: for each department the population figure has to be entered while the area of the departments is joined from the histogram of the departmental map.
Next, attribute tables are created for input maps depicting industrial regions, concentration of economic activities and main infrastructure. In the Colombia table with the population densities, weight values are assigned through a tabcalc formula; then an attribute map is derived.
A two-dimensional table is created in which for each combination of hazard classes and vulnerability classes an output risk class is assigned. The two-dimensional table is applied on the classified hazard map and the classified vulnerability map, and the risk map is obtained.
The Colombia map (with the Colombian departments) is crossed with the Risk map; in the cross table the number of pixels with high, medium and low risk can be seen for each Colombian department. These number of pixels with high risk, medium risk and low risk are joined from the cross table into three separate columns of table Colombia.


Finally, for each province, the percentage of high risk, medium risk and low risk is calculated with some tabcalc formulas. The purpose of Hazard, risk and vulnerability analysis (HRVA) is to help a community make risk-based choices to address vulnerabilities, mitigate hazards and prepare for response to and recovery from hazard events.
You have limited time and resources, so identify risk reduction action items for your greatest risks first. The local authority's assessment of the relative risk of occurrence and the potential impact on people and property of the emergencies or disasters that could affect all or any part of the jurisdictional area for which the local authority has responsibility. Download the complete step-by-step Hazard, Risk and Vulnerability Analysis (HRVA) Tool Kit. If you would like to consider and potentially do a more detailed Hazard Vulnerability Analysis the above worksheet and following information will assist you. At this stage in a traditional Hazard and Vulnerability Analysis, you would typically assess the probability or likelihood that this hazard could happen to your business. Note that you are not ranking the hazards against each other from highest to lowest probability. In the third column, rate the potential human impact of each hazard you have listed in the first column - in terms of the possibility of death or injury to your employees. You are not ranking the emergencies in terms of whether or not they are likely to happen - since you have already done that in the second column.
In the fourth column, you should assess the potential property & business impact of each hazard. Note that you are not ranking the hazards against each other from highest to lowest impact.
Total the scores for each hazard by multiplying column 2 (probability), column 3 (human impact) and column 4 (property & business impact). Analysis: PVP's hazard and vulnerability analysis indicates fire, natural disasters (such as flood, tornado, or hurricane), chemical terrorism and biological terrorism are the company's highest priority hazards. The susceptibility defined herein is independent of the characteristics of the acting agent, i.e. Such factors are category-dependent, and may be defined on the basis of existing literature or by other criteria set by the user. While such qualitative definition of intensity can be readily accepted, a univocal quantitative definition is not available at present.
Models for kinetic intensity (as function of landslide velocity) and kinematic intensity (as functions of displacements) are proposed.


In this approach a grid based Geographic information system (GIS) was used to construct a landslide hazard map for east part of Norway Romsdal region. Comparison with previous landslides shows that most of the previous landslides (70% - 95%) are within the high or medium susceptible areas.
To all classes in these maps, different weight values are assigned in their attribute table. Further, the the total number of pixels per department is joined from the cross table into table Colombia by using a join with with an aggregation. Tentative models for the calculation of the susceptibility for a number of categories of elements at risk are proposed i.e. Landslide intensity has been addressed and defined quantitatively using a variety of parameters. Kinematic intensity accounts for the effects of size-linked features of a reference landslide. The main difference between susceptibility and hazard is therefore that the latter considers the temporal factor, by estimating the probability of occurrence of the phenomenon within a specified period of time. Five layers of data with 30 ? 30 m resolution grid were superimposed to create the landslide susceptibility map. Hungr (1997) reports use of maximum velocity, total displacement, differential displacement (relative to points adjacent to the point under consideration), depth of the moving mass, depth of deposits after the movement ceases, depth of erosion, unit discharge, kinetic energy per unit area, maximum thrust, impact pressure, maximum normal or shear strain at or below ground surface.
The damage caused by a slow-moving landslide on a building is mainly due to the displacement (i.e.
Slope was given the most emphasis, followed by, topological index, density of vegetation, density of lineament and proximity to road networks. The quantification of susceptibility of persons includes: Susceptibility of persons in open spaces and vehicles (considering population density, income and age) and Susceptibility of persons in structures. A numerical rating system was applied and each of the five factors was grouped into three categories, and each category was assigned a value between 1 and 3, with 1 being least susceptible and 3 most susceptible to landslides. Although comprehensive risk analyses take into account all threats, we are simply including general categories.
