WP4: Socio-economic vulnerability and losses

WP4 Leader: KIT

Within this work package an estimation of socio economic losses due to physical damages on buildings will be performed in terms of casualties, displaced population, and other socio economic impacts. Furthermore, the social and economic impact due to seismic damages on utility networks, transportation infrastructures and critical facilities is going to be assessed through an indicator system that considers the strategic and economic importance of each element and system, and the interdependencies between elements and systems. Casualties and direct impact to “at risk” populations (e.g. shelter needs, hospital capacity, mobility impediment, etc.) will be estimated based on secondary data and fragility curves for buildings. Additionally, by considering the inherent factors of fragility of a person or community (i.e. age, disability, income, etc.) a set of social context conditions that aggravate the physical damages will be developed as indirect “impact” factors.

The methodology will combine the direct impact of expected physical damage to buildings, infrastructure and society, and indirect “impact” factors that account for the socio-economic fragility and resilience within the community or region. Furthermore, the strategic and economic importance of each utility and transportation element will be defined and connected with the physical damage based on appropriate classification schemes and indicators which describe the interdependence between the systems and the society. As such, the most critical elements of each network will be defined based on distribution and level of expected damages, geographical importance measures (populations and activities affected, interconnection with other systems etc) and network characteristics measures (capacity, flows etc).
