T35. Multihazard investigation, assessment and mapping techniques in urban areas

-

Congressi SGI-SIMP

Uncontrolled urban growth resulting from rapid population increase, combined with inadequate land planning and a lack of local authorities enforcing building standards, contributes to the increased vulnerability of populations in urban areas. Urban environments experience a process of "accumulation and amplification of multiple geo-hazards" caused by human activity, which increases the susceptibility of urban areas to various geological risks. The United Nations Development Programme (2021) emphasizes the significance of integrating urban geohazard reduction with national risk reduction efforts.
The risk assessment in urban areas often involves the qualitative and/or quantitative evaluation of many geological hazards, determined by combining the hazard's impact value with the vulnerability of the urban environment. Although in metropolitan areas the uncertainty of geodata sometimes prevents the quantitative resolution of this issue, most researchers agree that the combination of multiple geo-hazard maps with maps of urban environmental vulnerability represents the optimal solution.
This session aims to provide an overview of the tools and methods for multi-scale analysis that allow for the evaluation, including combined evaluation, of geo-risks in urban areas. The contributions may present: new experiments, applications of already established methods and tools, examples of best practices in hazard analysis, risk assessment (multi-risk), and land use planning.
