Abstract
The massive production of spatialized information following the passage of an extreme natural event brings newperspectives in their post-disaster analysis. Such data collected or produced during scientific retour d’expérience allows us to dynamically explore the cause-and-effect relationships between the hazard and the territorial consequences in both spatio-temporal and multi-scale dimensions. Mapping is questioned as a shared analysis tool conducive to interdisciplinary actions and as a useful knowledge support for their transfer to populations and risk management actors, during and after experience feedback.
