Until recently most regional maps of liquefaction hazard have been based primarily on geology, following the methodology of Youd and Perkins (1978). These maps predict the triggering of liquefaction and not its consequences. More than 50 of these maps, showing different areas of the United States, have been published since the methodology was first proposed (Power and Holzer 1996). Maps range in scale from 1:24,000 to 1:390,000. One shortcoming to these maps is that they usually depict the liquefaction hazard with a qualitative ranking, e.g., low, moderate, or high. Without specifying the hazard, these maps...
