T36. Sinkholes vs. land subsidence: assessment of the geological hazards and impacts on environment and society

Sinkholes represent a subtle geological hazard, often occurring without any precursory sign and characterized by high rapidity. These characteristics make them extremely dangerous, and a potential source of significant risks to society.
Land subsidence affects many of the world's major river deltas and alluvial coastal plains, inducing consequences such as aquifer salinization, inundation of lowlands, and coastal erosion. It is driven by tectonics, reduced fluvial sediment supply, sediment auto-compaction, and volcanism, in addition to anthropogenic causes, like subsurface fluid extraction.
The session intends to explore the recent advancements on natural and anthropogenic sinkholes, as well as on land subsidence in coastal plains, focusing on the understanding of how different factors contribute to these processes. Contributions dealing with multi-disciplinary approaches to single case studies, regional mapping and modelling are particularly encouraged, as they provide the basis for sustainable management practices.
