French Geological Survey

French Geological Survey

The BRGM is the French geological survey and France’s public reference institution in earth science applications for the management of surface and subsurface resources and risks. Its activities are geared to scientific research, support to public policy development and international cooperation.


The BRGM and risks

Understanding, anticipating, preventing, managing and adapting: our constant aim is to reduce the potential impacts of telluric risks (earthquakes, volcanic eruptions, tsunamis, landslides), climatic risks (land movements, clay soil shrinking and swelling), coastal risks (erosion and/or coastal flooding) and risks arising from human uses of the subsoil (storage reservoirs, sinkholes, etc.) in the context of global change.

To study understand and share knowledge about these risks and vulnerability to exposure, we design and operate a range of tools: surveillance systems, predictive models, risk mapping, databases, risk management models and scenarios, assessments of physical and systems vulnerability and multi-risk analysis methods. One of our key roles is to provide decision-makers with diagnostic and decision-support tools to aid risk prevention, spatial planning and crisis management.
