Seismic zone

Zone 2 of 5: low. 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.

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

23 ground movements recorded (landslides, rockfalls, collapses, mudflows…).
