Liquefied sites of the 2012 Emilia earthquake: a comprehensive database of the geological and geotechnical features (Quaternary alluvial Po plain, Italy)

Abstract This paper presents a comprehensive geological and geotechnical study of the whole area affected by liquefaction following 2012 Emilia earthquakes, including all available information from field reconnaissance surveys, in situ tests, laboratory analyses. The compilation was performed at 120 liquefied sites to verify validate reliability charts alluvial sediments, assess induced seismic sequence plain. results reveal wide range grain sizes (from clean sands sandy silts) compositional characteristics (quartz-rich litharenitic) ejecta, show strong relationship between stratigraphic architecture subsurface. availability tests makes it possible sediments with respect real observations. For analyzed case studies, use non-liquefiable crust provides better estimations manifestations when coupled thickness liquefiable layer rather than potential index. Altogether, this work international scientific community consistent database for in-depth earthquake studies.
