  ABSTRACT
  
  The U.S. Geological Survey has conducted a comprehensive 
  series of fault studies to determine the history and 
  extent of Quaternary deformation in the Yucca Mountain 
  area of southwestern Nevada as part of a broad, 
  multidisciplinary site-characterization program to 
  evaluate the suitability of the mountain to host a 
  geologic repository for the safe and permanent storage of 
  high-level radioactive wastes. The results of the 
  detailed studies reported here provide basic data that 
  are fundamental to assessing the risks posed by potential 
  future earthquakes and fault displacements with respect 
  to the design and long-term performance of the proposed 
  facilities. The scope and objectives of fault 
  investigations were largely guided by regulations 
  established by the U.S. Nuclear Regulatory Commission and 
  the U.S. Department of Energy for the siting of geologic 
  repositories for the storage of high-level radioactive 
  wastes.

  This report focuses primarily on eight faults within and 
  near Yucca Mountain that are known to have been active 
  during Quaternary time, as well as on two other 
  conspicuous fault systems in nearby areas that also 
  demonstrate neotectonic activity. The overall objective 
  was to obtain, for each individual fault or fault system, 
  definitive information on the number, magnitude, and 
  estimated dates of surface-rupturing paleoearthquakes. 
  Compiling such information involved extensive field 
  investigations, excavation and logging of trenches, 
  detailed descriptions of surficial deposits and soils, 
  and selected sampling and analyses for numerical age 
  determinations, all of which were performed in accordance 
  with a rigorous set of technical procedures and 
  guidelines that were formulated to comply with quality-
  assurance standards- an essential requirement for 
  activities related to the siting of nuclear facilities.

  Beyond the specific purpose of providing a basis for the 
  seismic-risk analysis of Yucca Mountain, the accumulated 
  data and resulting interpretations constitute a valuable 
  contribution to our knowledge and understanding of the 
  neotectonics in this part of the Basin and Range 
  Province. Faults in few other parts of the region have 
  been studied as thoroughly and comprehensively, and so 
  the pattern of Quaternary deformation within this limited 
  area may serve as an example of the structural relations 
  and the locations and magnitudes of potential future 
  earthquakes elsewhere in the Great Basin.
