Résumé
Vulnerability assessment is becoming more and more a crucial point to be tackled in the
framework of risk management of natural hazards. The assessment of the impact of these
hazards on built environment is essential to all the public authorities involved in risk
management and land use planning.
The purpose of the present study is to collect the most significant methodologies for
vulnerability assessment developed so far and propose some criteria to evaluate them in
order to suggest the most suitable to a specific territory, e.g. the Swiss, in this study.
This evaluation is carried out for three major gravitational natural hazards, i.e. landslides,
debris flows and rock falls.
