Session 2.2 GNGTS 2023 Fig. 1 – MILQ web service ( www.distav.unige.it/rsni/milq.php ). Although soil liquefaction is a highly localized phenomenon whose occurrence is intimately related to site-specific geological and geotechnical conditions, which deserve focused investigations, studies like the one presented here may serve as a guide to identify sites where the possibility of triggering liquefaction can be discounted within the land-use planning process. In other words, our results can be useful to guide land-use planners in deciding whether liquefaction is a hazard that needs to be considered within the planning processes or not. Furthermore, they can serve as a guide for recommending geological and geotechnical investigations aimed at the evaluation of liquefaction hazards or, conversely, rule out further studies with a consequent saving in efforts and money.
