Approved on 01/03/2019, this dataset delineates areas exposed to natural hazards within the municipality of Manigod, Haute-Savoie, France. It was produced by the Bureau de Recherches Géologiques et Minières (BRGM) as part of a regulatory Risk Prevention Plan (PPR). The hazard zones result from a synthesis of calculated, modelled, or observed hazard data, representing areas where the probability and intensity of dangerous phenomena have been assessed.
Use Cases
- Land-use planning and zoning restrictions based on mapped hazard intensity levels.
- Risk analysis for infrastructure development using the graduated hazard zoning.
- Emergency preparedness planning based on areas identified as exposed to one or more hazards.
- Studying the impact of protective structures, which are represented as still subject to hazard.
Strengths
- Hazard zones are the result of a synthesis using multiple sources of calculated, modelled, or observed data.
- Includes areas protected by structures, acknowledging their potential failure or inadequacy.
- Explicitly defines 'no or insignificant hazard zones' where the hazard has been studied and is nil.
