Earthquake Hazard: Liquefaction - Geologic Hazard Ordinance: Earthquake Hazard Component - Liquefaction Susceptibility. Liquefaction is a natural phenomenon in which saturated, sandy soils lose their strength and behave as liquid. Liquefaction is a caused by severe ground shaking during earthquake events. Areas are classified as having 'very low' to 'high' relative liquefaction susceptibility. Areas underlain by bedrock or peat are mapped separately as these earth materials are not liquefiable, although peat deposits may be subject to permanent ground deformation caused by earthquake shaking and require site-specific analysis under the International Building Code. Water and ice are also separately designated. Refer to Clark County Geologic Hazard Ordinance for more details (Clark County Code Section 40.430). |
