Critical infrastructures such as transportation systems, telecommunications networks, pipelines, and reservoirs are at risk of geohazards (e.g., landslides, earthquakes, floods) in many urban and rural areas worldwide. A key to safe and affordable operations of these types of infrastructure is an in-depth knowledge of their exposure and vulnerability to geologic hazards and the impact of damage experienced either locally or across the network. Fundamental understanding of hazard and risk involves (i) systematic identification and mapping of potential infrastructure exposure, (ii) integrated assessment of impact as result of damage, repair and/or mitigation, (iii) indirect losses from infrastructure disruption, (iv) consideration of interactions between hazards and/or cascades of hazards. This session welcomes contributions with a focus on geohazards risk assessment for critical infrastructures, and compilation of databases to record impact and elements at risk. We also encourage abstracts addressing the development and application of tools for cost modeling. The session is dedicated to contributions with national, regional, and local perspective and intends to bring together experts from science and practice as well as young scientists. We encourage poster submissions, and foresee a lively poster session couple with oral talks, and will, if appropriate, have an associated splinter discussion session.
