The state lists a volcano risk here: Piton de la Fournaise. Hazard risk is not graded in France: there is no national flood map, so a town outside the mapped areas can’t be called safe from floods.

Why hazards aren’t graded in France
In the UK, the Hazard risk grade is the share of homes in a mapped flood zone; in the U.S., it is FEMA’s modelled yearly damage to buildings. Both rest on maps that cover the whole country. France maps flood zones in detail only in its 125 areas at highest risk (TRI), so most towns have no figure, and a blank would read as “dry”. The state’s disaster declarations don’t fill the gap: they depend on the mayor applying, and they don’t line up with the mapped zones. So Bras-Panon has no Hazard grade, and its overall grade uses the other six subjects.
Everything on this page is shown as published. We’ll grade it when France publishes a national flood map.

Bras-Panon is outside the state’s detailed flood maps, so no flood zone shows here; that doesn’t mean no flood risk (below).
No detailed flood map for Bras-Panon
France maps flood zones in detail only in its areas at highest risk (TRI). Bras-Panon isn’t one, so there is no share of residents to show. That isn’t a clean bill of health: the state has declared 15 flood disasters here since 1982, the last in January 2024.
What the state does have for Bras-Panon: a flood risk plan (PPR), which maps the zones where building is restricted and a flood atlas (Cirque de salazie and Planèzes Est) showing where past floods reached.

Declarations by hazard · 1982–2025
Each line is a state order recognizing a natural disaster in the commune (“CatNat”), which lets insured owners claim. The latest flood began January 13, 2024; 9 flood declarations since 1995.
This count partly reflects how often a mayor applies for a declaration, so it isn’t compared between towns. It is a record of recognized claims, not a flood map. Source: GASPAR, Géorisques, file of 5 October 2026 (orders published to January 2026).
The state lists 9 hazards for Bras-Panon
Risk plans in force or in preparation, and the prefecture’s list of major risks.
| Hazard | Risk plan (PPR) | Listed by the prefecture |
|---|---|---|
| River flooding and runoff | Approved 2022 | ✓ |
| Coastal flooding | Approved 2025 | — |
| Landslides and rockfalls | Approved 2025 | ✓ |
| Earthquake | — | ✓ |
| Volcano | — | ✓ |
| Cyclone and storm | — | ✓ |
| Severe weather | — | ✓ |
| Forest fire | — | ✓ |
| Dangerous goods in transit | — | ✓ |
A risk plan (plan de prévention des risques, PPR) is the state’s map of where building is banned or restricted because of a hazard; it is attached to the town’s planning rules, and a seller or landlord must tell you if the home is in one. The prefecture’s file of major risks (DDRM) lists the hazards it expects in each commune.

Earthquake zone 2 (low)
What the ground under Bras-Panon does: national maps, the same for every town.
The national clay map (BRGM 2025) covers mainland France and Corsica only; overseas départements have none.
Bras-Panon is in zone 2 (low). New buildings must follow the earthquake building code (Eurocode 8) for their type. The zone sets building rules; it isn’t a forecast.
Clay: BRGM shrink-swell exposure map 2025, residents placed by INSEE’s 200 m grid. Earthquakes: national seismic zoning, decree of 22 October 2010.
Radon potential in Bras-Panon: category 1 of 3 (low)
Radon is a natural radioactive gas from granite and volcanic rock; it builds up indoors.
Bras-Panon is in category 1, the lowest: the rocks here release little radon.
The category describes the rocks under the commune, not any home: a test is the only way to know.

No industrial risk plan reaches Bras-Panon
Hazardous sites whose danger zone reaches the town, and the technological risks the prefecture lists.
| Dangerous goods in transit | road, rail, pipeline or waterway through the town |
Seveso sites store or use large amounts of dangerous substances; upper-tier sites have a risk plan around them. Distances are from the town’s center.

Volcano, cyclones and earthquakes in Bras-Panon
The hazards that set the overseas départements apart, as the state records them; not graded.
In a cyclone or volcanic alert, Météo-France and the prefecture set the alert level (yellow, orange, red, then violet for a cyclone); FR-Alert sends it to every phone in the area.

Being ready in Bras-Panon
Where France publishes warnings, and what to ask before you buy or rent.
- Météo-France’s vigilance map gives the day’s warnings, from yellow to red (violet for a cyclone).
- FR-Alert sends emergency alerts to every phone in the area; no sign-up needed.
- The seller or landlord must give you a risk statement (état des risques) for the address, listing the plans it is in.
- They must also tell you about any natural-disaster claim paid on the home.
- Géorisques gives the same statement for any address, free.
- Keep water, food, a radio and batteries for several days in cyclone season.
- The volcano observatory publishes Piton de la Fournaise’s alert level.
- The town hall’s safety plan (PCS) names the shelters.
- Ask for the risk statement and read which plans the address is in.
- Ask the town hall for its risk booklet (DICRIM) and safety plan (PCS).
- Check that home insurance includes natural-disaster cover (it comes with fire cover).
What this data can and can’t tell you
- Not graded. France has no national flood map, so we don’t grade hazard risk. Comparisons on this page are with other French towns of 2,500+, shown for context.
- Mapped areas only. Flood shares exist only where the state has mapped flooding in detail (the TRI areas). A town without a figure has no map, not no risk.
- Disaster declarations. A CatNat order recognizes a disaster so that insurers pay; it follows the commune’s application. The count partly reflects how often a mayor applies, so we show it but don’t compare towns on it.
- Plans. A risk plan maps where building is limited; it doesn’t say any one home will flood.
- Clay, earthquakes, radon. National maps of the ground: they describe susceptibility and set building rules, not damage or forecasts.

Is there radon in Bras-Panon?
Radon potential is category 1 of 3 (low). It describes the ground under the commune; only a test tells you a home’s level.

Why doesn’t Bras-Panon have a Hazard grade?
France maps flood zones in detail only in its areas at highest risk, so most towns would have no figure, and a blank would look like no risk. We show the data instead, and will grade it if France publishes a national flood map.
