RiskBox: Natural Hazards and Risks Analysis within the GIS GRASS
Presentation | Presented

In the future natural disasters are expected to increase due to climatic changes that strongly affect environmental, social and economical systems. For this reason and because of the limited resources, governments require analytical risk analysis for a better mitigation planning.
Risk analysis is a process to determine the nature and extent of risk by estimating potential hazards and evaluating existing conditions of vulnerability that could pose a potential threat or harm to people, property, livelihoods and environment. In those studies three different phases are required:
1)Hazard assessment: the location, frequency and intensity of events;
2)Vulnerability assessment: the degree of loss due to a given severity hazard occurrence;
3)Exposure assessment: the quantification of the spatial distribution and the estimated value of the potential targets.
Rink analysis should be addressed by GISs that have the ability to deal with the spatial nature of the problem and to link different professional disciplines.
For these reasons the Institute of Earth Sciences is developing the RiskBox: a series of tools and procedures fully GIS integrated able to guarantee the required interoperability and accessibility among stakeholders.
The designed system is entirely based upon the FOSS4G environment (R statistical package, GRASS GIS, PostGIS, php mapscript, etc.) and is composed by:
1)kernel: developed within the GIS GRASS. Different hazard models and analysis procedures will be implemented as independent modules.
2)GUI: developed in desktop/Web environment. It can provide user friendly access to the modules.
