Mapping soil liquefaction susceptibility across Europe using the analytic hierarchy process

Abstract Mapping the susceptibility of earthquake-induced soil liquefaction at continental scale is a challenge. Susceptibility soils to tendency certain geomaterials undergo severe stiffness degradation and loss shear strength. The latter could be induced by cyclic loading seismic events. surface evidence local phenomenon, detailed geotechnical field investigations are not available for regional studies, mention scales. literature review shows in several European countries, yet, comprehensive picture available. This work aims develop methodology assess Europe using geospatial parameters weighted via Analytic Hierarchy Process (AHP). major outcome study novel Liquefaction map (LSE), based on building ten different macro-units liquefaction. These have been delineated this order homogenous areas from geological, physiographical, geomorphological points view. adopted input depositional environment sediments, distance water bodies (coast rivers), compound topographic index (as proxy saturation). resolution LSE 900 × m. results cross-compared with maps region Greece (i.e. Thrace), Portugal, Bulgaria, sites where manifestations occurred across Europe. can identify large susceptible including also territories characterized low seismicity potentially affected anthropogenic seismicity.
