Earthquakes and radon

Seismic zone

Zone 2 of 5: low. This regulatory zoning, in force since 2011, sets the rules for earthquake-resistant construction.

Radon potential

Category 3 of 3: significant potential. At least part of the commune has higher-than-average uranium content. Radon is a naturally occurring radioactive gas that can build up in poorly ventilated rooms.

Beneath the town hall

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

Cavities and ground movements

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

No underground cavity recorded (quarries, cellars, military works, natural cavities…).

No ground movement recorded (landslides, rockfalls, collapses, mudflows…).

Risk prevention plans

  • PPRN-I - BV Gapeau [ Pierrefeu-du-Var ] 2014

    Natural risk prevention plan.

The zoning and regulations of each plan, which may prohibit or restrict building, can be consulted at the town hall and on Géorisques.
