Seismic zone

Zone 3 of 5: moderate. This regulatory zoning, in force since 2011, sets the rules for earthquake-resistant construction.

Radon potential

Category 2 of 3: low potential, with aggravating factors. Geological features (faults, mine workings, thermal springs) can make it easier for radon to reach buildings. Radon is a naturally occurring radioactive gas that can build up in poorly ventilated rooms.

What BRGM maps say at the town hall. They describe that single point: elsewhere in the commune, the ground may be quite different.

• Shrink-swell clays

• Rising groundwater

• Underground cavities

• Ground movements

• Earthquakes

• Nature of the ground

Recorded across the whole commune by BRGM, in its national databases of underground cavities and ground movements.

5 underground cavities recorded (quarries, cellars, military works, natural cavities…).

1 ground movement recorded (landslides, rockfalls, collapses, mudflows…).
