Soil and Subsoil Risk
Ineris’ soil/subsoil risk expertise falls within the realm of geosciences: geomechanics, geology, geotechnics, hydrogeology, geochemistry, etc. This type of risk is classed as accidental risk, but differentiated in the industrial and technological sense, being solely of anthropogenic origin (caused by human activity). Economic activities involving exploitation of the subsoil (mines, quarries, etc.) can create the conditions for the occurrence of dangerous natural phenomena (ground movement, floods, etc.).
Ineris has thus developed competencies in areas such as ground movement which affect the exploitation of ground-level and subterranean activities: collapse of cavities, mudslides and rockfalls, compacting and swelling of the ground, induced seismicity. These phenomena have one point in common, they are all due to the effect of gravity, which is at the heart of Ineris' expertise, but gravitational effects are propagated either from ground level up (collapsing cavities or land ground movement), or from above (mudslides and rockfalls).
Ineris' expertise in ground movement applies to all subterranean economic activities and by extension, to all new forms of subterranean operations: energy storage, capture, transport and storage of CO2, geothermal ... As part of natural risk prevention, the Institute studies the risk of ground movement and cavity collapse well beyond the limits of economic activities. There is a significant overlap between risks in an economic activity and those in town planning.
