Analysis for Liquefaction: Empirical Approach

An improved analytical method to calculate the likelihood of soil liquefaction is described. The method is based on an expanded list of case histories of liquefaction and no-liquefaction and employs earthquake magnitude and hypocentral distance to describe the intensity of shaking at a site. The new list of case histories is compiled from a complete re-evaluation of previously published case histories and field data observed in more recent earthquakes. Specific applications of the proposed procedure are described and an example analysis is presented
