Multi hazard and Multi risk definitions - jcgomezz/Building_taxonomy GitHub Wiki

'Multi-hazard risk', refers to the risk arising from multiple hazards (Kappes et al., 2012a), whereas 'Multi-risk', has been related to two different definitions:

Multiple risks such as economic, ecological, social, etc. It determines the whole risk from several hazards, taking into account possible hazards and vulnerability interactions entailing both a multi-hazard and multi-vulnerability perspective. In the RIESGOS initiative, the second definition of the multi-risk is considered, and mainly the physical vulnerability will be analyzed, including the analysis of the physical fragility of the considered structural- exposed- components, with a further study of their failure models (Coburn et al., 1994). More information about these regards can be read here: Multi-hazard risk and Multi-risk assessments

Being focused on the physical fragility analysis, by considering a Multi-hazard- building -exposure taxonomy, this initiative is aimed to be build a pilot exposure taxonomy for multi-risk assessment on the framework of the RIESGOS project. Widely used structural taxonomies include: ATC-13 FEMA 154, HAZUS, European Macroseismic Scale 1998 (EMS-98), PAGER-STR, and the World Housing Encyclopedia (WHE) .
