Development of a Liquefaction Opportunity Map for Cache Valley, Utah

A liquefaction opportunity map was developed for Cache Valley, Utah. The study was the initial phase to determine the potential for liquefaction in Cache Valley. The method used in this study to develop the liquefaction opportunity map was based on a procedure developed by Youd and Perkins (1977). This opportunity map is proposed to be combined with a map delineating liquefaction susceptible soils to produce a liquefaction potential map. The liquefaction susceptibility map is being developed in a companion study. The liquefaction potential map will assist in the evaluation of earthquake response in general and microzonation in particular. The liquefaction potential map may also be used by contractors, consultants, governmental organizations, etc., for preliminary planning and decision making to determine the suitability of a given site
