Varen municipality in the Tarn-et-Garonne department of France has areas exposed to geological hazards like block falls, as defined in its natural risk prevention plan. The dataset, produced by the Bureau de Recherches Géologiques et Minières and last updated in July 2021, represents hazard zones graduated by intensity level. It includes areas protected by structures considered at risk and excludes zones where hazard studies found no significant risk.
Use Cases
- Modeling landslide and rockfall risk based on hazard intensity zoning.
- Informing land-use planning and construction regulations based on multi-hazard exposure codes.
- Assessing the effectiveness of protective structures in hazard zones.
Strengths
- Produced by a national geological research organization (BRGM).
- Includes zones protected by structures, accounting for potential failure.
- Explicitly excludes areas where hazard was studied and found to be nil.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
