Abstract: A brief description of a recently developed methodology to evaluate liquefaction hazard at a site is presented. In this method, uncertainty and scatter in the data are considered rigorously. The method is applicable to projects both at the micro and macro level. In the latter case, this method can be incorporated in the GIS to develop regional liquefaction hazard maps. These maps are needed for routing of major lifelines and siting of major facilities.
