Potential of landslide (dependent variable) and a set of intrinsic properties ( independent variables) were constructed by using geographic information system (gis) the gis-based landslide hazard analysis illustrated the spatial relevancy of the prediction with objectivity of the model in the similar terrains study area. P aleotti and r chowdhury, “landslide hazard assessment: summary review and new perspectives,” bulletin of engineering geology and the environment, vol s lee, “application of logistic regression model and its validation for landslide susceptibility mapping using gis and remote sensing data,” international journal. Abstract the landslide susceptibility was assessed based on multivariation analysis the input parameters were represented by lithology, land use, slope inclination and average annual precipitation these parameters were evaluated as independent variables, and the existing landslides as dependent. Landslide hazard assessment and risk reduction can be accomplished by providing risk managers with easily accessible, continuous, and accurate information about landslide occurrence thus, an accurate susceptibility mapping can be key information for a large variety of users from both private and.

Layers have been generated using remote sensing and gis techniques the concept of landslide susceptibility and landslide susceptibility assessment have been introduced in the past couple of decades there have been numerous studies involving landslide hazard evaluation (guzetti et al, 1999) landslide hazard. Ural hazards in many countries, the annual loss of lives and property due to landslides are greater than any other natural disasters, including earth- quakes, floods, and windstorms globally, land- landslide susceptibility assessment using mathematical methods in gis, qianyang china 1401 figure 1 location of the. In the recent years, the ever-increasing diffusion of gis technology has facilitated the application of quantitative techniques in landslide hazard assessment today a wider spectrum of instability.
The landslide inventory is a fundamental prerequisite for landslide hazard analysis based on gis keyword: landslide, himalaya, gis, remote sensing image, survey of india etc introduction when a rock has been steep slopes: terrain characteristics are very important for assessment of potential areas of landslide. Panikkar and subramaniyan (1997) carried out landslide hazard assessment using gis based weighted overlay method in the area around dehradun and massori of uttar pradesh, currently uttarakhand in india the study revealed that rapid deforestation and urbanization have triggered landslides in the. Landslide hazard assessment using remote sensing and gis techniques submitted to the university of london, uk for the degree of doctor of philosophy philippa jane mason imperial college of science, technology and medicine, university of london, uk august, 1998 london. Hazard, vulnerability and capacity mapping for landslides risk analysis using geographic information system (gis) hadmoko d, lavigne f, sartohadi j and dan winaryo p 2010 landslide hazard an risk assessment and their apllication in risk management and landuse planning in eastern flank of menoreh.
In this study landslide occurrences and their relationships with various event controlling parameters have been evaluated using gis and remote sensing techniques statistical relationships of these parameters with landslide occurrences were converted into risk susceptibility priority numbers these numbers were re scaled.

Budget provided and development priority given by the government different approaches for landslide hazard assessment using gis there are many approaches to assessing slope stability and landslide hazards mostly using geospatial analysis (sidle et al, 1985 dietrich et al, 1986 montgomery and. Abstract the purpose of present study is the assessment of landslide hazard using weights-of-evidence model in southern part of golestan province, iran in the first stage, landslide locations were identified in the study area from interpretation of aerial photographs, and field surveys in the second stage, twelve data layers. Susceptibility, since 495% of past landslides fell within the very high susceptibility category, which confirms the model's performance the outcomes of this study will be useful for future initiatives related to landslide risk reduction and management keywords: disaster gis hazard landslide rwanda.
Parameters are prepared in gis and logistic regression analysis is done by using statistical package for landslide hazard assessment between besi sahar and tal area in marsyangdi river basin, west nepal geographic information system (gis) to map landslide hazards in a mountainous environment (chen and. Landslide hazard is one of the major environmental hazards in geomorphic studies in mountainous areas for helping the planners in selection of suitable locations to implement development projects, a.
Abstract: geographical information systems (gis) are powerful for spatial analysis, and the analytic hierarchy process (ahp) has certain advantages in multi-index integrated evaluation the combination of gis with ahp provides an effective measure for hazard assessment of landslides based on detailed field observations. Large landslides are one of the main natural hazards in kyrgyzstan because of the high number of landslides and their relative inaccessibility in mountainous terrain the potential of satellite remote sensing in combination with gis-based analysis has been investigated in the frame of a collaboration with the ministry of. Landslide susceptibility maps help communities understand where future landslides may occur dogami engineering geologist bill burns narrates a presentation. The city with a population of 33,000 people is located in an area, which is regularly affected by flooding, landslides and earthquakes in order to assist the local emergency commission and the municipality, a pilot study was carried out in the development of a gis –based system for risk assessment and management.
