Leveling data collected in Las Vegas Valley are compatible with the interpretation that ongoing land-surface displacements related to ground-water withdrawal may be precursory to fault offset of the land surface. Zones of potential faulting intersect regions of intense urban development. The degree of risk and the potential economic consequences from possible surface faulting cannot be assessed adequately without additional data and analysis of the relation between surface faulting and ground-water withdrawal.
