Preventing surface and subsurface risks

BRGM conducts research to improve the understanding and management of surface and subsurface risks. It designs and disseminates diagnostic and decision-making tools to support risk prevention.

To help anticipate, prevent and adapt to surface and subsurface risks, BRGM implements research activities and diagnostic and decision-support tools.

Preventing natural and human-induced risks

BRGM studies potential surface and subsurface risks, whether of natural or human origin, and in particular:

  • Geological risks: earthquakes, ground instability, cavity collapse, volcanic eruptions, shrinking and swelling of clay soils, etc.

                           More information about BRGM activities on geological risks

  • Coastal risks: marine submersion (storms, hurricanes, tsunamis) and coastline retreat, including climate change effects (e.g. sea-level rise)

More information about BRGM activities on coastal risks

  • Human-induced risks arising from underground storage of CO2, energy, etc. and subsurface operations

Understanding risks and assessing vulnerability

BRGM’s work in this field focuses in particular on:

  • understanding the phenomena at work and studies of the mechanisms governing geological risks,
  • risk mapping and modelling,
  • studies of the physical and systemic vulnerability of exposed sites and developing multi-risk methodologies,
  • risk assessments and surveillance,
  • risk reduction and prevention methods, training and information tools and emergency preparedness,
  • assessing the consequences of climate change.

Risk diagnoses and decision support

One of BRGM’s roles is to provide decision-makers with diagnostic and decision-making tools to support risk prevention and sustainable rural and urban planning.

BRGM designs and implements a range of tools for this purpose:  monitoring systems, predictive models, risk maps, databases, software and digital simulation platforms, zoning plans, risk scenarios, risk reduction measures, etc.

BRGM also conducts expert studies and expert third-party assessments of natural (geological and coastal) risks and human-induced risks.
