Evaluation of possibility for liquefaction susceptibility and setting bases for liquefaction zonation in Croatia

Implementing of geologic, geotechnical site conditions and prior seismic behaviour of the area into a map results in earthquake-hazard maps, which can be used as a predictive tool for seismic policy development and emergency planning. Possible applications of these maps are various and include: identification of geological vulnerable areas with critical facilities, selection of suitable areas for new facilities, prioritization of seismic upgrading programs, risk estimation etc. Croatia is a state with high seismic activity, and there were several well-documented occurrences of liquefaction during earthquakes (Dubrovnik 1667 ; Virovitica, 1757 ; Zagreb, 1880). To author's knowledge, there was no research for evaluating the possibility of onset of liquefaction at the territory of Croatia. Basic approach for the liquefaction zonation in Croatia, as well as basis for specific liquefaction resistance evaluation will be presented in this paper.
