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.
