The "Pôle Alpin d’études et de recherche pour la prévention des Risques Naturels" (PARN) association (non-profit organization law 1901) gathers 9 member organizations among research centers and universities of the Rhône-Alpes region that have an activity of study and research on natural hazards. The association was created in 1988 as one of the recommendations of the “Isère Département Pilote” operation in the field of natural and technological risks: to make an effort in the field of research to develop more effective and less expensive methods. The cluster has been created with the following objectives: • Bring together organizations with an activity of study and research in the field of natural hazards in order to develop coordinated research programs and so remedy the fragmentation of efforts in this area • Develop efficient scientific and technical tools and make them available to public authorities and operational services to improve the prediction and prevention of natural hazards.
