by T. Leslie Youd, Brigham Young Univ, United States,



Document Type: Proceeding Paper

Part of: Seismic Design and Construction of Complex Civil Engineering Systems

Abstract:

Technique for assessing liquefaction hazard are considered herein: Methods for compiling regional opportunity maps are reviewed and a crude national map is developed. Compilation of regional liquefaction severity index maps is also examined. Techniques for compiling area susceptibilty and potential maps are evaluated and example maps presented. Rapid evaluations using available site information are reviewed. Available site information might include subsurface data from the site or nearby areas, occurrence or lack of studies of the area. General predictions of site hazard also may be made from regional and area liquefaction hazard maps.
