A Geospatial Approach for Mapping the Earthquake-Induced Liquefaction Risk at the European Scale

This paper presents a geospatial methodology for zoning the earthquake-induced soil liquefaction risk at continental scale and set-up in Geographic Information System (GIS) environment by coupling data-driven knowledge-driven approaches. It is worth mentioning that phenomenon of instability occurring very local spatial scale; thus, mega-zonation hard facing challenge. Since from natural disasters convolution hazard, vulnerability, exposure, mapping based on combination explanatory variables, available scale, previously listed three assumed independent random variables. First, applying prediction model calibrated Europe, probability mapped whole continent. Then, Analytical Hierarchy Process (AHP) adopted to identify areas have high liquefaction, taking into account proxy data exposure. The maps are computed different levels severity ground shaking specified return periods (i.e., 475, 975, 2475 years). A broad variety stakeholders would benefit outcomes this study, such as civil protection organizations, insurance re-insurance companies, infrastructure operators.
