Description: Liquefaction susceptibility is a rating that represents the degree to which any given geologic map unit is susceptible to liquefaction during an earthquake, assuming full soil saturation. Liquefaction susceptibility classes were based on data from Youd and Perkins (1978). Liquefaction classes range from none to very high, which range numerically from 0 - 5, respectively. We created this liquefaction dataset by compiling the best available surficial geologic maps, amending linework to align to features visible in the lidar, and assigning geologic units liquefaction susceptibility classes. The liquefaction potential of landslide geologic units is not included in this dataset.
