Abstract

Liquefaction represents one of the most dramatic effects that may occur during an earthquake. Several controlling factors may influence liquefaction occurrence, such as the earthquake magnitude, the peak ground acceleration, the depth of the groundwater table and the geological context. In particular, the thickness of the potentially liquefiable layers, the grain size of the sediments, the compaction degree and the interaction between different lay-ers may strongly influence the phenomena. Hence, a deep understanding of the liquefying de-posits is fundamental for the hazard assessment. During the Emilia (Northern Italy) earth-quake sequence of May-June 2012 , several liquefaction manifestations were observed. In this work, a 3D geological model for liquefaction hazard assessment is presented for the Cavezzo municipality, which was affected by liquefaction phenomena. The study was performed in the framework of the European project Horizon 2020 "LIQUEFACT” using an interdisciplinary methodological approach involving geologists, geomorphologists, sedimentologists, engineer-ing geologists and geotechnical engineers.
